EMC: Spindle drive options ?

Hi,

I'm now committed to converting my Denford TRIAC mill to EMC - I'll
be using the exisiting steppers via Gecko 210's but what are my
options for spindle speed control?

The spindle motor is three phase 240 /440v (ie star or delta) 0.37KW
which on the original machine was driven by a VFD (1985 vintage) that
has been 'hacked' to interface it. I expect that I'll have to
buy a new VFD but what are the options for speed control & direction
with EMC? Any pitfalls to avoid ? Anyone got a suitable VFD ?

Any help much appreciated
