Harbor Freight is where I got both of mine and they both work very well and were cheap. You need the right kind of blaster for the job, a pressure blaster will remove anything pretty fast but can warp sheet metal or damage delicate parts. A siphon blaster is less likely to damage things but takes forever on painted parts and tends to clog. On both be ready to buy replacement tips regularly. You need a very large compressor too as they require a lot of air to run (cfm cubic feet per minute) or you will blast a very short time and wait for the compressor to catch up flogging the compressor. You will also need to decide what medium you want to use and that is usually in direct relation to the material the item to be blasted is made of and how delicate it is. It is very easy to ruin things with a blaster.

I learned all I need to know about life by killing smart people and eating their brains.
