Never heard of them and the bed is small but maybe an alternative for the future if they make bigger machines?
Someone on the forum was thinking of getting one, not sure if he did. They do do bigger machines:

Redsail,Cutting Plotter,Vinyl plotter,Vinyl cutter

I don't like their advertising / description:

It says on the 300x200, 'All three axis are driven with anti backlash lead screws' which isn't great due to the backlash, but then a bit later in the description it says 'High Quality Ball Screw anti backlash bearings throughout', so which is it?
It says, Industrial Strength High Torque 4Amp 48V 128step stepper motors, but then states 'Stepper Motors: Step Angle: 1.8 degree, Current: 3.0A/phase ' which is the standard 200step/rev and a different current... so again which is it? Probably the latter but if they can't even get the most basic specifications right in the advert one does wonder what else might be wrong.
Also says 'High Grade Construction, will cut hard metals' which seems unlikely. Before considering it you need to find what type of rails it actually uses - i.e. supported (can just see those on the bed) or not and also if it uses ballscrews.

Anyway, with regards to making your own I can't really add or offer anything different to what Jazz has said since I'm currently tied up making another one.
