Well, it really depends on what you are going to do with it mostly. If you are going to do mostly bodies, go with something like a Badger 150 or 360, or an Iwata HP-SB. For Illustration I use a Iwata CM. For T-shirts, there are different requirements as well. Go to
www.dixieart.com and look around there. They have a lot of good information and great prices. You can also check out the forum on
