I can't really lay claim to being an indie "snob" or even being on the cutting edge, as their was no "scene" in my town. The closest we came is that several so-so metal bands played the local dive bars, and one of the bands actually got good and got signed (Bobaflex).
Lately, I've been abandoning my pop-metal wannabe teen angst sorta shit for more indie stuff. I'd say my biggest find yet would have been Deathcab for Cutie and The Postal Service WAY before most people in this area were listening to them (and before DCFC went to a major). I was still a year or so behind picking up the older stuff, but for this area (rural West Virginia) they're still relatively unknown, with most people only knowing them as "that band with the song about souls and bodies".
I'm definitely trying to get into a lot more diverse groups so as to build my indie "cred" and allow me to look down my nose at others while discussing my vinyl collection.
Next paycheck is definitely going to picking up some of the groups mentioned in this thread.
And I'd have to add, even though they're not exactly indie (I'm not familiar with their label, and not sure of it's actual status) I'm diggin' the fuck outta The Perishers right now. Even if they're not technically "indie" it's definitely a rare band for this area.
