They used to be called TIP. Unless they have changed radically in the last ten years or so, they are a top notch outfit. My dad's and my friend's pressure blasters came from TIP. Great blasters for the price. My dad built his blasting cabinet using their plans kit. My friend got his Quincy compressor from them many years ago, and at work we used to order stuff from them all the time. No complaints. Good products, good service, good price.
Well, maybe one little complaint. We ordered a lid for the pressure blaster at work and it was like $6.95 or $7.95, something like that. We needed a tight-fitting lid to keep dirt and junk out of the blaster while it wasn't in use. What they sent us was a Frizbee with their logo on it. I mean, it was a real Frizbee, actually made by Wham-O for like seven bucks. It fit like a glove, but we couldn't help but feel a little cheated. But, hey, at least we could toss it around after work.
