Do you need portability? If so, there are the popular Park Tool folding models... I haven't worked with one myself, so I can't comment beyond the portability aspect and the nice spring-loaded clamps.

If stationary would suit your needs, check out the wall-mount and bench-mount models. If you like deluxe tools and don't need portability, consider their PRS-3OS.
I have an older PRS-2 with a custom-made 100-8C clamp, myself. Definitely
not portable!
