A/C Kit Vintage vs. Old Air vs. Classic Air

[1badcholo]

So my LQ4 install is almost complete. I have a factory a/c cab and factory a/c controls and I need a complete system for my 72.
So who do you recommend there are a few companies out there. My controls are in good shape but other than that I need a whole system.
Which is the best bang for the buck it seams like $1400-1500 is the most likely cost.
My questions are quality, durabilty, fit & finish what do you all recommend.
Thanks!
