gmax 1.5 and 1.5XT Review?

Anyone have a review on these, particularly the XT? I'm curious about the accuracy, durability (though it looks like the plastic parts aren't in tooo critical areas), and how having 1 axis being performed by the moving bed works for tall objects. Will the moving bed cause tall objects to tilt, sway, warp, etc?
Overall this printer looks really cool and I like the idea of it being so customizable. I also love the large build volume, but also wonder if it will have trouble with ABS on taller parts as it gets further from the heated bed and it is fully open. Pictures of prints look very good though.

For the record, I'm a noob to 3D printing, don't yet have a printer, and am doing research to figure out what I want.

Has anyone used one that has had any results, whether good or bad?
