Clamp On Cable Stop in the UK?

[Me]

Hi, I'm looking for a clamp on cable stop to allow me to run Vbrakes on my older Ti mtb. I saw a
thread on this a couple day ago however all the shops mentioned were in the USA.

It clamps to the top tube giving me an additional cable stop.

Does anyone know where I can get one of these Tektro ones like in the link- or something similar
in the UK?

Cheers
