Thanks for the welcome, Irving, and many thanks for the web site link - it looks to be pretty good from what I've seen so far.

You're right, the other site in the UK I'd found was MD. The puzzle with them is that their eBay prices don't seem to tally with their direct web site pricing, with the eBay packages being a fair bit cheaper. Unfortunately, none of their eBay package deals is really the right sort of size for what I have in mind - maybe that's why they're a bit cheaper.

I'd better get back to looking at the "slides and ballscrews" site!
