I just bought this grinder:

My first grinder ever. Up until now, I've had to buy preground beans. This machine has impressed me, though I really have no comparison. My only gripe is you can only remove the upper section of the burr for cleaning. But for the price I got it for ($119 + $5 shipping) it's definitely worth it.
Probably not your issue, as others have stated, just thought it might be helpful since you are probably still going to be in the market for a burr grinder at some point.
