As someone who previously tried to avoid 80/20 (T-slot style) at all costs, being on a new team with limited resources meant trying to use more COTS items. To be honest, for the amount of time it took us to assemble our lift (frc2168) this year I couldn't be happier. We even ended up using the 80/20 and associated linear slides for our minibot deployment. As a side note, spray lithium made the lift operature much better than it did "dry".

My Suggestions:
For your chassis - Stick with kitframe. Its free, and great for what it does. Built correctly a kitframe will out perform 80%+ of other robots

For superstrutures - For COTS linear motion its hard to beat, but for most other things it turns out to be really heavy (0.5lbs/foot for the 1"x1"). Look into using square stock and gussets or the 80/20 quickframe.

Note that other companies make comparable products to 80/20 such as Bosch extrusion, However 80/20 seems to have a larger selection of accessories.
