I got a Rhino, for my GFs McDermott, a couple Christmases ago, and she likes it. That prompted at few others on our 8 ball team to get either shafts, or full cues from Rhino. Everyone is very happy with them.
I've seen ads for Bizu Billiards, and they have a carbon fiber shaft for $103 with free shipping.
Haven't seen anything about it on this forum yet, but I'm sure it'll end up getting reviewed here eventually.
Hard to beat that price for a shaft.
