[Birdman of Ballard]

I'm just returning to flying after decades of inactivity. Back when I did my initial training, headsets were not seen (not in the planes I flew at least....it has been a LONG time!). Nowadays, headsets seem to be pretty much everywhere, and as I'm flying in insanely complex/congested airspace (Seattle, WA, with 3 large airports clustered within spitting distance of each other; it seems pretty crazy to me), it has been suggested to me that being very sharp with ATC communications is a good idea, and having a decent headset just seems to be expected. OK, seems reasonable.

Right now, about all I know about headsets is that Dave Clark's are light green.

Any pointers on beginning the process of shopping for a headset? What should I look for? Where's the best place to shop and buy? Is there any good (unbiased) source of comparisons/ratings/etc.? I don't need something that's needlessly gold-plated, but am willing to spend what I need to to get the right unit (whatever THAT turns out to be).

Thanks!
