We use a lot of 1x1 Angle in both 1/16 and 1/8 depending on the application

We also used last year some 3x5 box for a gearbox, 1/8th thick. We also use 1in flat and 4in flat for a lot of applications,We use 1x1 1/8th thickness for drive bases and structure, along side 1x2. We don't use tubing that much, but we did use it for supports this year

1) 80/20 I know you said no t-slots but it is so useful especially for rookie teams & prototyping. You can get a deep discount if you tell your distributor you are a First team when you order it.
2) The Andymark C channel. reference holes are nice
3)The VEX 2x4x.1 rect. tube reference holes & lines are nice.
4)1x1x.125 angle. easier to properly torque nuts than in tube.
5)1x1x.125 square tube. About the same weight as 1" 80/20. Slightly stiffer.
6) 1/2 hex. Great for shafting
