Aftermarket A/C systems

Anyone had any experience with adding aftermarket a/c to their ride? It's not an a body but I've got a pretty sweet 83 ram 2wd pick up that I'd like to add a/c to. I've looked around some but can anyone suggest a budget friendly company for this. Also how well does it work if anyone has knowledge. I'd hate to pay out a pile of cash and it looks like crap and doesn't cool well. Thanks in advance.

I have done 2 GM cars with Vintage Air. I gave the fit and quality a good 7 out of a 10. As for the performance, a 10 out of a 10. 32 degrees on both installations so they are efficient. Personally unless it was a factory AC vehicle I would just throw an underdash unit in next time. Someone else will chime in I am sure but that is my experience with atleast one of the popular companies....
