Just to add my 2p-worth, I've got the Xyron personal cutting system (do they still make it?) and its OK. Just OK. I don't have room to leave it out all the time, but it doesn't take long to plug in, and everything cust in 3 sizes BUT you have to buy extra books (it comes with one alphabet (shadowed) and basic shapes) and I've had problems with thinner paper tearing, or the paper skiidding so it doesn't cut. And there's a fair bit of card wastage 9but you can use leftovers of 4" square so that's a good use of oddments).

It all comes down to space, budget and personal taste in the end (but I would like a big shot....)
