I have one of those portable Campbell-Hausfield?? ones.

With a decent compressor I can do rims, headers, intakes etc.
I use it outside & put up rolled plastic against the garage wall & ground. I recover most of the media & clean it with some handheld mesh screens. Cheap & effective as long as your neighbours are oblivious to noise & dust.
An old welding helmet & gloves, shiek yerbouti head scarf & coveralls complete the look.
