I don't know about the uk (i am from the Netherlands), but if the mentioned bender is not what you need, I have this one, which seems identical to the one you first mentioned:
Www.hbm-machines.com/producten/plaatbewerking/metaalbuigers/hbm-ub-1-metaalbuiger
They do ship internationally, but its weight is 35 kg!
If you need translation, just ask.
