Hey Brandon,
I can't vouch for any of these other knobs, but you can check them out for your self, and decide if you like them.
www.m3motorworks.com carries knobs by AC Schnitzer, Hamann, M-motorworks, AA, and Rouge Engineering.
They also have matching e-brake levers for every knob except the Hamann one.
www.amimotorsports.com has about 300 different MOMO shift knob and e-brake choices. They also sell the matching boots, and (in some cases) adaptors that you will need to fit everything onto your car.
Hope this helps. Let me know if you need any thing else.

P.S. I think UUC is a good company. Their knob just happened to have a flaw in it. I will still be ordering parts from them in the future.
