I have one, I like it for the most part. It is very different than the MFT. There are tons of threads about it. It is a supplement for the MFT, not a replacement.
In the US they were going for somewhere between $525 and $650 or so. One company cleared them out for half price. For half price they are worth it. Closer to retail they are not, in my opinion.
I have the 3 version, and not the Professional. I use it as a mobile work bench for cutting, sanding, etc. Ideally, you would have 2 MFT's and a Walko bench. Two MFT's would work well for cutting longer portions of sheet goods.
There were some threads about the bamboo tops separating when wet. You may wish to investigate this further.
