@ tom. interesting - will put some feelers out ;)....
It might be worth making it known to Carnival, etc, that you'd be interested if they came across something. 18 months ago I picked up two 58cm Vivalos for £450 (£225 each). For comparison, I could have bought a 56cm Vivalo (identical colours to the 58cm ones), but it would have cost me £50 more.
I know that the exchange rate has moved and that I bought when everyone was having to dump their Vivalos, etc, but you should probably be able to pick up a minority interest sized frame from one of the less prestigious marques (Samson, Panasonic, Anchor, etc) for about £300.
