Get the best one you can, otherwise it will jam up like a First Generation PSA10. (sorry PSA owners, I just had to use that). I have a cheap one and it works, but is starting to fall apart, and doesn't always cleanly cut. Speaking of cutting, Kamikoto knives of Japan has changed their marketing strategy. Their knives are in the $400 to $600 range, but now if you advance order them you can pick them up in the $125 to $200 range. I have one coming July 1, I will give a report on it.
