John,
I recntly picked up a Kenwood KDC-255U from Fry's.com for $69.99 with free shipping. Came with USB and Aux inputs on the front. I would check both Fry's and Crutchfields for items going on sale.
If FM reception is an issue check the unit you intend to buy for it's FM sensitivity rating. The lower the rating, supposedly, the better the ability to receive FM stations. However since there is no uniform code for rating stereo's I am not sure comparing one brand to another is an accurate way to compare, but it is something to look at. If you have USB and Aux inputs you will probably be listening to a lot less FM anyway.
