that cheap one seems to fit the bill nicely for this type of application, and the price is right if it works.
I use a cheap harbor freight cabinet and bought 50lbs of glass bead, and only use it only stuff that is relatively clean, so it lasts a long time. ie, no heavy grease and rust. descale and degrease the best you can, then use the glassbeader.
for that small of a bead blasting rig, I think I'd find a decent sized carboard box, and use it as a backstop to reclaim some of the beads....a makeshift cabinet for cheap, if you will. even something like a rubbermaid container, but just make sure to wear eye protection.
