I couldn't really suggest one brand of player over another, but I do recommend you get your player from Crutchfield (
www.crutchfield.com). Their prices are always pretty good and their support department kicks ass. They also include all of the extras you'll need to install the player in your car.
When it comes to a brand of player, I've bought a Blaupunkt and have been very happy with it. Though, a friend of mine has had some minor problems with her Blaupunkt (when you eject the CD is doesn't come out all of the way).
