Non-owner opinion: It's a decent box. I've messed around with one in the store (or a similar model), and it seems okay for a home-user. Pretty light gauge IIRC, but if you're just looking for a little box for home, it should work fine. I get around with a few craftsman bb units, one roller and a 5 drawer top. I don't think I'll ever need more than that.
You can read the reviews on the website you linked to as well for a better idea (since they've actually used it!) Seems like they took away the liners in the picture, so you might have to buy them seperately (30-50$?)
Here's my take: If you're cutting Bowden Cables or other linear cables with coverings similar to that, you'll practically need the specialized tool to get the job done properly, every time. It's like trying to cut thicker cables with dykes alone, you really need the specific shears to cut them. What are you going to be doing with the cutters? If you only need to use them a few times, you might be better off trying to go to a local bike shop and asking to use theirs. You might be able to get away with that. If you'll need to use them all the time (forgive me, I haven't read into the thread much), then you'll want to own a pair. Those fantastico cutters are great, but only for general cutting duties, not cables. I'd buy a pair myself if I didn't have a similar version from Knipex. As far as using them for different purposes, they look like they're made specifically to cut those darn cables, and that's about it. Same thing with very small cutting pliers made specifically for electronics, you'll probably mess the edges up if you wanna cut something out of the designed use.
