I recommend using MTC (Make the Cut) with whatever machine you decide on - the tracing capabilities are the easiest I've used. There are a lot of cutters out there and most owners like theirs; I have several and like them all. There is a comparison at paperthreads.com
Make the Cut link Make the Cut!™ - Offical Website - Greatest cutter software yet created!
BTW I have no vested interest...just an owner of a few cutters (electronic and manual)
