Thanks ladies, i called paperlane, they said they have the hand held punch style rounder.
But i'm looking for something heavier and more industrial, like the ones you clamp onto a table, insert a few pages of thick stock, and press the lever down...
I have hundreds of business and christmas cards to do, so not sure if the hand punch will be able to cope.
But if i dont get one soon, i just might have to buy the corner rounder from paperlane to start of with..
