Bravo Company, Rock River, DPMS, Bushmaster, and other brand name carry handles will all be around a Hundred Dollars or so new. However, I have purchased old Colt carry handles for $10.00 which were like new, from gun/pawn shops.
No experience with UTG carry handles but have purchased some of their AK stuff which has held up well. No personal experience but I have heard about problems with no name discount/bargain priced carry handles, i.e. small parts being loose or not holding after adjusting, etc.
AR15.com used to have some kind of a data base type post listing the forge marks on various brands of carry handles which helped with identifying their manufacturer.
