How much do you want to spend? How heavy a machine are you willing to deal with (i.e.,
50lbs, 100lbs, 500lbs, 1500lbs ? )
I have a Grizzly G8689 <http://www.grizzly.com/products/item.cfm?itemnumber=G8689&site=grizzly>
that I'm pretty happy with but I had to do a number of mods. Also for building the jBot
robot it was not quite big enough to mill the 5x20 inch chassis plates and we had to use a
big Bridgeport. But for all the small parts it was fine. Dandy, infact. Mostly aluminum
<http://www.geology.smu.edu/~dpa-www/robo/jbot/aut_2510x.jpg> and some nylon
<http://www.geology.smu.edu/~dpa-www/robo/jbot/aut_2546x.jpg> and some steel fiddley bits.
Generally bigger is better if you have the $$ and the space and can handle the weight.
Do you have any particular machines in mind?
