A little extreme lol, if you want to get an Xcarve just get one no need to defend it but seriously check out the shapeoko 3 first as they are about the same price and the Xcarve is a shapeoko v2 check out it's history and the differences.

Version 3 is a lot more solid than the Xcarve but has minor wobble in the Z axis, Xcarve has more flex in the gantry but more solid Z axis.

Personally if I had to choose between the 2 I would go with the shapeoko v3 and remake the Z axis plate to be solid which a lot of people do. You really should check out the shapeoko forums and Xcarve forums to really get an idea of what you can do with one.
