+1 on the 6004. Excellent machine. Love love love the SC mounting. It's really nice to be able to turn one knob to get things centered. I have a 6004 6pt SC with the 4 tooth clamps, and I have a 5800 2pt SC with even newer clamps (which are 5 tooth, but about as slim as the 4 tooth).
Honestly not sure which clamps I like better. They're both quite good.
