Before I started the resto on the Sport Satellite, I bought a HOBO unit

Found that the finer #7 (I think it is) glass bead left a great finish, might have taken longer to strip crap off, but no real pitting . . . anyhow, it was big enough for larger things like a wheel (took a while to do) . . . I have a Campbell Hausfeld compressor that really had to work, so would drain the air tank, then stop and let it fill up and go again . . . anyhow, for my use it worked great ! Took up too much space, so after I was all done, sold to a buddy . . .

Guess it all depends on what your are going to use it for and how long you want to use it . . .

Cheers
