Pricing a Simple, Useful Desktop App

I've grown tired of giving software away. So, I want to experiment with recouping some of the costs. I'm wrestling with pricing. I don't want to go too low as I'm concerned people will think it's cheap, and not too high as I want it to be easily affordable by average folks. I see value in micro-payments, but google check-out charges 2.9% + .30 cents a pop. So, I need the range (I think) to be $5.00 to $25.00. I feel both extremes are bad. Any suggestions?
