For cheap, look for Johnson. They are a Korean (I believe) OEM who have begun releasing product under their own name.

Hohner is the best, but pricy. Last I checked Blues Harps and Marine Bands were in the $25-$30 range. When I was actively playing I carried six or eight to accommodate various guitar keys, plus a couple of chromatics and a Melodica. Hardly cost effective unless you are a pro, or just have the do-re-mi.

Note: If you want to play blues, you need to buy one (or more) in the key(s) that is a fourth above the tonic of the key you will be playing in.
