I have the 50 lb setup and it works ok with the large 175 psi 25 gal Sears compresser.
I'm currently doing a Frame up restoration on one of my Triumphs. It took me about a week to do the frame. The compresser can't keep up, but I save the sand so I stop frequently to gather up the sand, adjust the equipment, change the lens in my hood and any other little tasks that need doing while the compresser catches up.
With a small compresser don't go any larger than 1/4 " on the nozzles. The gun has a air orifice and a nozzle. Make sure that both are right for the setup you want. (small orifice and small nozzle etc.) I'm quite happy with the setup.
Get a hood, their a pain to wear but really work well keeping the sand off your head and from going down your shirt.
I just got the larger Eastwood Bench top sand blasting cabinet and it works great. I'm going to hook up an inside light and a foot pedal. I also have a small shop vac hooked up to it. You pretty much have to use a vac or your garage fills up with dust. A small 30 dollar one works fine. I also use a small orifice and a 13/64' nozzle and I'm able to maintain 90 psi with no problem.
