I have quite a few of the very cheap €-store ones, but they've proven to be disappointments all; dull or dulled easily, wonky/wobly construction, material too soft etc, etc.
I then was able to buy a brand new GW one for only a couple of €, (I would never have paid full price for it though) and this finally is a cutter I can rely on and does what it's supposed to do.
So even though you shouldn't pay out of your nose for one, you should absolutely not settle on the dirt cheap ones from Action or $/€/£ stores either, as you'll only get frustrated by them...
