How about.. you build HALF, and Link Mirror does the rest?
The Link Mirror Symmetry System
What is it?
To say it simply, it's a Mirror function, like you'd see in 3d editing software, allowing you to build only half of your project, and let the mirror finish the other half. It is designed to work on linksets, meaning linkset rules apply. Such as 255 prim limit, and the link distance limit. You can however, USE AS MANY LINKSETS AS YOU WANT! Everything in this system is as automated as SL allows. Scripts are automatically deployed, automatically removed, automatically linked, if you have more than one of your own mirrors in your build area, the linksets will only use the closest one as a reference point. Meaning this system is very dynamic and allows for multiple creations at the same time!
What can it do?
It's capable of mirroring almost any linkset you can throw at it, textures included, there are limitations though. These are Nano(cubes, cylinders or prisms with Dimples(this is an SL Bug), nano spheres and sculpts will give you no trouble however) prims and Mega prims. Because of the way nano and mega prims are/were made, it's not possible to re-create them through script.
Link Mirror DOES NOT REQUIRE YOU TO START FROM A SPECIFIC PRIM, it gives the option to deploy the scripts automatically allowing you to mirror previously made linksets, you can however start from a scripted prim, which would remove the need to deploy the scripts. Either way, the option is yours.
Beyond those 2 limitations however, the Link Mirror will Perfectly mirror Sculpted Prims (thanks to Viewer 1.21), flexi's, and any prim you want to throw at it.
Link Mirror will also copy your prims inventories, and will copy the scripts running (if they're running on the original linkset)
Watch it in Action!

I would suggest watching checking out the in-world demo to see this system in action. Nothing paints a clearer picture than a live demo. The youTube video's will also give you a fantastic demo of what this system does!
Link Mirror requires that you have full permissions on the object you wish to mirror, otherwise textures will not be copied, also anything created with the mirror will be in your name.

NEWLY ADDED FEATURES IN V2.1
Auto-Linking
Due to popular request, auto linking has been added to the mirror!
Mirror Detection
On top of being able to use thousand hundred linksets at a time, you can now use a thousand mirrors at a time! Lets say you've got three projects on the go, and each uses the mirror, well normally you'd of had to move the mirror to accommodate each project. Now though, each linkset will simply use the mirror closest to it as its reference point!
Fixed Flexi Visual Bug
As you know this was a very simple fix, just area select the flexi's and they popped back into shape, as it was only a visual bug and cured itself rather quickly. But i took it upon myself even to cure that minor nuisance. So now flexi's should be created with a Very brief visual bug (no more than a second) then they should automatically snap to proper scale.
Auto Script deletion of new linksets
Now that the mirror links automatically, i figured what better than to have the scripts removed automatically after linking? And so that's what i did! Now when the mirror process completes, the new linkset is literally ready to be picked up and used.
Please note: the original linkset still retains the scripts until you remove them, those will not automatically delete as you may wish to make changes to your project then mirror it again, but can still be removed with 'Rem.Scripts' whenever you're completely finished!
ADDED FEATURES IN V2
Multiple Linksets!
No longer do you have to work on one project at a time, start 2, start a dozen, doesn't matter, the mirror will handle each one individually, and automatically, requires no setup to use more than one linkset. So building an avatar or a house even, has never been easier.
Deployment of a Pre-Loaded Prim!
If you prefer to build with the shift+drag method rather than deployment method, you're able to load the mirror with a pre-loaded prim, and have it drop it for you when you're ready to begin.
Auto-Placement of a Deployed Linkset!
After deploying scripts in your linkset, after the pick up and drop, you can now "Reposition" your linkset to have it move itself back to where it was when you deployed the scripts!
Up to 10 times faster than V1
Laggy sims plagued V1, but no more. V2 functions fine on every laggy sim
I've used quite a few different mirror systems building my avatars, and so far this is easily the best one yet. It mirrors EVERYTHING I need it to and I simply LOVE using this tool. Its taken a lot of long hours out of building every near-symmetrical or symmetrical thing I have ever made. I just wish the maker had created it sooner.
