Hi,
Cheers for the advice. I've seen it on thomann.de and part of me is tempted to order it in the knowledge I can send it back, but if there is one in the UK somewhere I'd still rather try it first (after all trying a £1500+ instrument in a shop for a few hours and then buying it is still a matter of confidence - especially given I don't play EUB at the moment).
If I get one I'll certainly report back (and would be happy for others who are interested to try it). I'm fairly sure I will, but it may take a few months, depends on finances and being able to try one. Promenade Music seems like a good bet (they are here: www.promenademusic.co.uk) and I've just emailed them FAO of Gary.
All the best,
Tom
