Steinberger Synapse strap hooks

[BottomEndian]

I'm looking to get hold of a Steinberger Synapse strap hook to whack on my newly-acquired Hohner B2AV. For those not in the know, it's this:

It shifts the position your headless cricket-bat bass sits over to the right a bit and helps stop neck-dive (normal strap-button position on the B2AV is basically where the screws are on that picture).

Trouble is, they don't seem to be available in the UK. Anybody know anywhere I can get hold of one? Or do I need to find a US-based bass-brother to ship one over for me?

Or if there's an alternative (and I mean a [i]fully formed, ready-to-fit[/i] alternative, cos metalwork and me don't mix), I'd be interested to hear.
