Anyone have any experience with these or spindles like them:

3KW AIR-COOLE MOTOR SPINDLE & MATCHING INVERTER VFD e - eBay (item 250739491599 end time Feb-05-11 20:46:50 PST)

I'm kind of torn between something like that and a PC 890 for my first machine.

Would something like the link above just be a waste of money? Do you really need to spend $2k on a 2kW spindle to get something decent?
