I've got one of these

It's a Chinese-made cabinet, but a decent size without being massive. I'd seen good reviews online for the price and I'd got quite a few little blast cleaning jobs that needed doing and it would have cost me more than that to get them done by someone else so thought I'd try it and if I got enough use out of it I could always buy something bigger and better later on, but I've had plenty of use out of it and it's a good cabinet, especially for that money.

I'd already got a huge compressor, so no worries there. The blast media runs through and doesn't require changing very often.

I'ev also got one of their pot sand blasters too for larger jobs and it's also very good for a cheap price.
