After a lot of faffing about (over 3 months), it turned out I had a faulty cutter. The guy replaced it no problem, and I must say, it's brill
It's a 54 inch cutter, and cost me, including delivery, about £260.
It will cut precisely at as little as 3mm circles (rhinestones) it even cuts the heavy duty stencil film without thinking about it.
It has a pressure range of 1-400g, and is really quick and easy to use.
So, cheap is best isn't always the case, but in this instance, it's worked for me
