To be perfectly honest I couldn't tell any difference between this and the Kress 800 on the few jobs I have run off.
Only using a 1/8" single flute router cutter at 12,000 rpm on modest cuts so not the best way to test.

Just got some nice 1mm ball nose end mills and some white corrian and I want to do a picture of the grandkids in Photo Vee carve.

At this, size 8" x 6" and using the 1mm cutter it will need the whole 24,0000rpm and the cutting time will be about 5 hours so that will be a good test.
