sand blast cabinet update help please

that is just the name of the site. i did some research and these are 3 retired guys that want to keep busy. they had the same concerns that a lot of people do with the siphon type blaster cabinet. won't siphon, plugs up, having to blow back through the system to get it to work. same problems i have. i wanted to see what was out there and after i found the tacoma company, i figured there might be something else out there at a better price. i think i found it. it beats buying another blast cabinet. if i can make a few improvements(still remains to be seen) and it works a lot better, i will feel the money is well spent. on another note, i have an old greyco parts washer that i will probably upgrade with parts from them also.
