I'm in need of a BB ISIS style.

For some E-Bay bargain 2006 Race Face Ride XC cranks...(yes I know I went flying in the face of recent advice and bought some cranks which will apparently snap if I fart on them...but they were reeealy cheap).

I figured I'd spend a little more on the BB..something around £30-£40.

SKF.

Yup SKF is the only one worth buying IMO. You can pick up the BXC-300 off Stif for £42 posted

I think I'll invest my pennies in that, Looks like it was designed to simply work, I like that.

Is it the standard, BB tool to install?

No, it's like a Truvativ so you'll need the XTR BB tool
