Default [Q] Best place for digitizer part?

Well, as luck would have it I tried replacing my broken glass but damaged the black screen that attaches to the LCD in the process. I guess I need a whole new digitizer assembly now. Where is the best place to get them? Looks like all the different parts stores around the web (Amazon, ebay) all have generic knock offs. I'm OK with that as long as they work, but the reviews don't ever seem stellar. Any advice? Thanks
