We had a vex team back in middle school (2148E) and bought a kit with some add-ons to prototype from home. Only one piece of C channel ever got cut (seriously), so the kit is like new condition at a heavy discount. Its not V5 but y’all probly know if you can still trade it in for V5 or not. Details on the add on kits and extras are in the craigslist link
The price is $500, with an original buy price of over &1,700.
*We are in the Dallas area
