Which is the best aftermarket AC unit?

What aftermarket unit's are you guys using and how do you like them for installation, fitting, and cooling. I was looking at Boundstaffpress's homepage and he's not happy with his Classic Auto Air.
I have several of these older trucks one I had planned on using a Vintage air unit which I've always have heard good things about, the other was on a hot rod site.
It looked like the older under dash ac units.

I thought of putting it in a older work truck.

Tell me your and good and bad experiences please. Also, I have a 67 and 68 parts truck with ALL the air components but looking at them seems like I'd be adding 300lbs to my truck for old technology.

I don't want to spend big $$ for marginal cooling.
