The best you can get is a Marco (formerly Lindsay), pots come in all sizes but the small 35 lb pots are awesome, made just like big sandblasters but on a smaller scale. I am a sandblaster, been doing it on the side for about 10 yrs, and I would recommend a Marco, you can run it on about a 5-6 hp compressor, check out they're site, they're high but blow that harbor freight and northern tool crap away. DuPont Star Blast abrasive is good stuff too.
