Really, the only turn-key or near turn-key game in town (that I'm aware of anyway) is going to be vivaek, as stepper monkey mentioned. This gantry type mill has a literally unbelieveable price of $2355.
http://www.vivaek.com/cnc3002.html It's really difficult to get a grasp of the actual physical size. It appears to be a sizeable machine, but it only weighs 210 lbs. I would question it's robustness, or apparent lack-of, considering that a little X2 weighs in over 150 lbs.
Here's a turn-key converted X2 mill, but it's priced @ a rather hefty $3500 (not worth it, imho)
