yeah. i was looking at those also. i will likely purchase one of the 990oz/in ($99.00) motors this week and give it a shot with the xylotex and homebrew unipolar drivers ive got.. the kellinginc is local to me, and only about 5 miles from where i go to work every day. i am waiting for gecko drives to arrive, and when they do i will know more. it seems to me of the motors on the site, the $49 NEMA23 450oz/in(or whatever) and the NEMA34 990oz/in for $99 seem to offer the best values... it costs alot more to goto the larger motors.. $20 more, or 20% for a 170oz/in gain in power.. i suppose it depends on the application. I would imagine these large motors in a router would produce very quick and powerfull movement. I am thinking the extra power these things would generate on my fairly small system will equal greater accuracy as lost steps wont be a problem.. More like the thing having enouch power to wrench itself apart could be a problem..
