Hi... I'm a bit off the beaten path, Bangor, Maine.Where are you located at BruceW? I just put a set on one of my kits (along with Ddrum triggers).
There are a couple of fantastic drum shops available to me, one in Portland (2ish hours drive) and one in Portsmouth, NH (2.5-3 hours drive) away. My local music store has had the low volume Sabians before, I haven't checked recently. Pretty sure there won't be anything with those heads near me either.
