hi mate. i'm in the uk too. check out motioncontrolproducts.co.uk maybe .com. they are reasonably cheap and do some 1.8NM motors for about £21 each which i will be purchasing. Also think about using EN24 bright bar for the linear guides instead of precision ground bar. its accurate and hard, and its so much cheaper than ground bar. the bar i got is within 1thou of size along a 3 meter length. that cost about £12.50 for a 3 meter length instead of about £2 for 100mm of ground bar. for oilite bearings check out bearingboys.co.uk, they are pretty good and cheap.
