Wow. Unless someone comes forth with a good recommendation, maybe I should just try to install it myself...

I hear the Crutchfield guides are really good if you've got the tools, time and patience. I think this may be the route I choose to go. I've talked to two installers so far where I live, and both of them stuck their noses in the air the minute I mentioned that I was going to provide my own head unit.
