Hi guys, Any idea where I can find mini hold down clamps for a T-slot table?

I need something like this: UJK Technology Hold Down Clamp - Router Table Accessories - Router Tables - Routers & Trimmers - Power Tools | Axminster.co.uk
except that is probably too big for my machine table.

Rockler in the US do a mini version of their hold down clamps. They are 3" long: Mini Deluxe Hold-Down Clamp - Special Application Clamps - Clamps
except they don't seem to ship to the UK. Any ideas where I might find something similar in the UK?
