Need replacement side mirror?

Hello, can anyone recommend the best solution for replacing my passenger side mirror on a 2000 Tahoe? I just need the mirror/glass only (but will purchase the entire mirror if it costs about the same as the glass). The dealer sells the mirror for about $60.00 and I've seen aftermarket mirrors for about the same price. I have the heated mirror with the puddle light (no auto dimming).

Any help appreciated.

i got a whole new passanger side mirror and housing on ebay for about $40.00. I dont remember the ebay store name, but there is a few of them. mine was for a 1998 tahoe, and it looked brand new. i almost thought about scratching it up...lol
