There are numerous vendors who sell what appears to be the exact same unit, and all between $99 adn $109. The new versions are even rebuildable.
CAS, Kirban, Cotton's, Red Armstrong (Quad Air), RamChargers, Conley's, and many more. I would call your favorite pick, and just make sure they have it in stock and ready to ship. I've been waiting on mine from CAS for over three weeks now, but I'm learning that's the norm with them. I believe RamChargers sells CAS stuff too, and would suggest using an actual vendor for anything CAS makes, as opposed to dealing directly with Charged Air. At least until he starts shipping on time.
