Sand-blasting cabinets?

I bought one just like the one Summit sells except for the color. Seems like it was about $180 shipped, maybe less. It was from one of those outfits that have semi trailers full of stuff & come to town for a day to have a sale. I didn't buy one when they were in town but later found it on their website on sale for less with free shipping. Can't remember the brand, but the cabinet is blue & yellow. Haven't set it up because I haven't got the heat straightened out in my shop yet. Priorities.
