Air Conditioning for a driver?

[muddpile]

Since I am planning on making my truck a daily-mobile after its done, I figure it might as well be comfortable. What does everyone reccommend for an air conditioning setup. I want my dash to look reasonably stock if at all possible, but could care less what it looks like under the hood. Which setup works best, costs least, is the easiest to install, etc. I don't need show quality billet or anything, just something that looks good and performs well too. My truck is not a factory air truck. Thanks!
