Query re Flashguns in the UK

I made more use of my flashgun (a simple tilt head gun costing £25 about
five years ago) at a conference over the past weekend than I have over
the past couple of years. It made me wonder if a 'better' gun would be
worth the effort. So I did a web search for 'recommended' guns.

Apart from TTL guns for my gear (especially Metz), two that were highly
commended were:

        Vivitar 285HV   (on sale in the USA at $89)
        Sunpak 383

However, a Google search indicates that neither appear to be on sale in
the UK.

I quite like the Vivitar as it has a (manual) zoom.

Although I'm not immediately looking for one, I am baffled at the
absence of two well known brands in the UK. Has anyone any explanations?
