When you're ready, email them for a quote with exact sizes.

I was also concerned about ordering from BST initially, but there are a lot of examples of people here using them. Jazz probably keeps them in business singlehandedly. You can pay with PayPal via AliExpress. AliExpress hold the PayPal payment in escrow until the package arrives and then you release it to the seller. You're also doubley protected by PayPal, and even further if you use a credit card, so it's really no risk at all.

I paid roughly £1100 delivered including all import duty for four ballscrews (30cm 1605, 1m 1610 and two 1m 2010s) with associated ballnuts, ballnut mounts, BK and BF bearings (upgraded to AC I think), all custom machined to my exact lengths and to allow pulleys, all of my hiwin 20mm linear rail (2x1.2m, 2x1m and 2x35cm) and 12 hiwin carriages, and a 2.2kW spindle plus VFD with collets and water pump and spindle mount.

Sounds like a lot of money, but those three things were the most expensive components and about 1/3rd of the total build cost.

I won't go into further detail about the import duty, but trust me don't be concerned. You'll get a text or email when the parcel arrives in the UK and you just pay online.
