is anyone running the £88 free delivery chinese usb bob's

[nobby]

i do have a
standard - if you can call it that? parallel bob
plus a pci parrallel port, in the event it does go mammary glands up, but thought I'd like to try it usb first, well for the £88 quid anyways
if i have problems I can switch in the latter. or even have the bob in a different box altogether.

what was foxing me was the power supply to the parallel bob is 36 volts, but on the usb, its usb powered and 5volts
= don't like electrics too much.
its a shame they simply don't make a bob card to fit in a pci slot.

p.s. can i cut 20mm foam pvc plastic with that 710 watt motor on full chat in a single pass, and that said, what bits do i now buy
twin flute up or down?
single flute?
