Thanks for all the great info, Phil! I have decided to go with the HF machine:
http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=93252 The things I'm making fit in my hand, so I don't need a huge floor model, thankfully. I was just wondering if these cheap machines would do anything at all, and it sounds like they will. It seems more like the medium and tumble-time will make the real difference here. I think I'll give your plasti-dip suggestion a tryout, too, as I'm worried about eating away the bowl with certain more abrasive media. I think I'll see what the internet has to say about homemade/found media, too, as some of the abrasives on the page you linked are pretty pricey for my hobby-only needs.
