gorilla makes a good one. Volks are also good.
Defently DON'T get Kyokugens. Not only are they weak as hell, and the key is too (strips out VERY easily) to actually get a key is probally the easiest task ever. I called up, said my key had striped, even though I had always used a trq wrench. They said, oh, well no problem, we will send you one out, should have it in two days. Two days, it shows up. No questions asked.
