I like it alot.
I like the access to the cutting platform and the absence of moving parts makes for easier wiring.
Flex obviously could be an issue with the gantry but you have heaps of opportunity to beef it.
The biggest weakness that will need attending to is the possible racking of the moving table and if you look at this current thread (http://www.cnczone.com/forums/showthread.php?t=51485) , you will see how to solve it .... easily!
Good luck and keep us posted.
