Here is a link to the model I bought from Harbor Freight:

I had to buy a pressure regulator (max. pressure of 90 PSI for the gun), and some attachment parts, for an additional $10.  The hopper empties out rather quickly.  I did not do the entire bike, but I did do a fair amount of it.  

It really cleaned up a lot of blemishes.  I must have filled that reservoir around 8-10 times, before I emptied out that 2 lb. box of Baking Soda.  It was a bit tedious, but not too bad.  Seeing the effects of the rust, and other blemishes, coming off the bike, was very encouraging.  Gotta go put it to work on the Voyager, now.  Time to crack that second 2 lb. box of Arm & Hammer.

One word of caution on using Baking Soda to blast on anything:  be sure to wash the object thoroughly, with soap and water, if you plan to paint it -- this stuff will cause paint adhesion problems after the paint cures...  My understanding is that the paint will bubble up, with time, unless the surface is very thoroughly cleaned of all traces of Baking Soda.  Cheers!
