Many thanks for the welcome,
Must admit it took a while of googling around to find out what all the different 'ER' numbers meant and what was needed, and found the ER32 set goes from 1.5, to 20mm so a good range.
RDG are selling a boxed set on ePray for a shade over a hundred quid delivered!
Includes the 2MT chuck, 18 collets and 'C' spanner, seems to be the best bang for buck.
The beauty of these collets, is there's a 1mm leeway on each collet, so cutting tools don't have to be spot on size.

You're right about location, we've only about a 500 yard walk to get our feet wet, and as there's damn all in the way of shopping facilities here anyway, the only wandering I generally do for esoteric stuff like this is via a pc keyboard.
