mitch, here is a spool holer i printed yesterday at .2 height on the m2. it is black and a perfectly straight column so a good example of layer alignment and smooth surface. this is done in abs. at .1 it would look even better. .2 never looks bad, hell i print at .3 all the time but i do notice a difference between .1 and .2 so i dont know what those other guys were talking about. i do have to say this though, on any printer its as much the operator as it is the printer. its all about settings, tuning and getting the max out of the hardware. i have seen tons of crappy prints come off an m2 and i have also seen beautiful prints come off the m2 as well. i have a client with a 100k stratasys dimension and the spool holder i n the pic is of as good or better quality that would come off that machine.
