What stinking router must I purchase to use with my Quest DSL?

I am getting fed up with QWest, but at the moment it wouldn’t make much sense finically to end my subscription with them.
OKay, let me explain as simply as possible. I need a router that supports UPnP and can be used as a modem for my DSL on QWest.
When i call QWest, they give the run around, bouncing from one numb brain to another, most of which have no idea what I mean when I say UPnP. So I can’t get a strait answer out them, their website doesn’t tell me junk, other then some models come in Blue! oooohhh, I don’t give a side F*** I need UPnP so I can utilize “Back To My Mac” and a few other off site networking “toys.” Mainly apps on my iPhone.
Thus, to summarize, can anyone tell me what modem I should get with UPnP that will work for QWest DSL.
