I have no idea why AMain has the CXL for so much.

I'd definitely take that over the discounted CX. CXL has soft-weave chassis, new steering components, new top deck, new swaybars, new arms for the swaybars, new hinge pin geometry...
Buying new, though, I'd probably go for a TC6.1. Better parts support, cheaper parts, better aftermarket support, and better support at the track. Fit and finish may not be perfect, but mine went together straight and is fast. Although I think I'm going to part with it to simplify my spares situation, and focus on driving and setup skills for another year.
