Looks good Roy, and considering its use of expensive ball screws, the price is 
pretty decent.  They do not say what it weighs, but $150 for shipping says 
there is a bit of beef there too.  Bear in mind that any such tabletop 
machine is going to need a very well built steel table in order to support it 
as it moves around without sagging as the gantry weight shifts.

The video makes it look slow, rated at 50 ipm it can move about 2 times as 
fast as the video shows.  I peak out at 30 ipm on the xy, so I'd guess maybe 
that was moving at 25 when they made the video.

I would suspect, but I haven't checked, that almost any old $50 goodwill 
computer with a 400mhz+ cpu and 256megs of memory a 4GB hard drive and a good 
parport(some are short on drive), running kubuntu 6.06 + EMC2 could run that 
machine very nicely.  I'm using an xp-1400 running at 1600mhz, & a 46GB drive 
only because I had it, and TBT it has enough overkill that I can carve parts, 
carry on a conversation with the authors of EMC on IRC, and browse the web 
watching you-tube clips all at the same time.
