I’ve just bought one of these in 1200 x 1200 (code B4WB1212BO) size and thought others may be interested. It knocked together in about ten minutes, came with some plastic feet and caps for the top of the angles, feels very robust and fits my XXL really nicely with just a little space left over at the front. I’ve stashed stock material on the shelf underneath and will likely fasten it to the walls of my workshop to increase stability further. At the highest setting the machine feels comfortable and easy to work at. I also thought that with the pre-made holes in the legs, it would be easy enough to fasten on boards to create an enclosure.
I’ve no affiliation to the company, but it looks like a reasonably decent solution for not a lot of money so thought I’d share.
Tom.
