A couple of months ago I got the chance to have a play with one of these setup's. I has put a 1800x220 peice of flooring onto it and used their Rotex 150 sander to take the varnish off... Boy, that thing holds well.. Easy to move around. But... It's pretty expensive. However, I'm doing an office at the moment with lot's of edge banding. I would not get my money back straight away (as I do as justification for most of my tools) but in a few goes you would. Screw clamping it all down, just place it on and - STUCK !!
If it were £500-600 I'd buy without a question...
However... most places do discounts even on FESTOOL - I'm so tight, I HAVE to have a discount, so perhaps I will look at it again on the next kitchen I do...
