Ebay Redsail clone?

At ebay is a auction with quite big laser cutter /itm/High-Precise-50W-CO2-Laser-Engraving-Cutting-Machine-Engraver-Cutter-USB-Port-CE-/201430056910 One from lads I know got this and is a happy - no hangouts/software issues, cut clean enough (previously user of K40 small laser) - but is this wort this money? I suppose this will be 50W laser, as does not look for "long tube".
I'm at Europe, so plus for me is no extra tax/duty on it. For me looks like a Redsail "clone" - but how it should be located on list from this great thread: http://www.cnczone.com/forums/genera...196-forum.html any good/bad sides? I plan to use it co cut plywood/thin wood (~3mm, occasionally up to 4-5mm - but really rarely) and engrave mostly vector lines - so work will be same as cutting, but with lower power (not bitmap "scanning-similar" riding left and right with blinking laser)

P.S. - Is this same laser cutter? http://www.cnczone.com/forums/showth...%20right%20now.

The components and the build quality is the same as Shenhui's. It is a decent machine for hobby projects, not for serious work. Still, it will be an excellent upgrade from K40 because of its size, controller and software.
