Where's a good place to buy a 3-phase motor in UK?

I'm after a 3.7 - 4kW 3-phase motor. Ideally flange mounted, 3000rpm (2 pole) and 230V. Something like TEC or WEG or better.

Where can I find one of these at a good price? Looks as if RRSP is around £250-300 but wondering if there's a better price out there, being a Scottish blooded Yorkshireman and all.

I got a 2.2kW one via John Stevenson for under £100 a couple of years ago, so he seemed to know a cost effective source. Pity we can't ask him any more.
