overhead consoles?

[cstanley]

i've been thinking about putting a new overhead console in my truck. i'm looking at a number of different styles out of late model cars and trucks on ebay, and wondered if anyone had experience with some that may fit better than others (width between visors, slope of the roof, drop depth.) i'm looking at some from the most recent chevy trucks and tahoes, as well as some of the dodge ones.

anthing fit particularly well? anything to stay away from?

thanks
