I've got a Virtuoisi Euphonium - had it just over 2 years - and whilst it has a lovely tone the valves are, to be frank, just rubbish. They had plastic valve guards (?) which had to be replaced wth metal ones after just a year and now two of the valves won't come out of their barrels without forcing them as though they are "too tight" - so its back to the repairers again I am seriously tempted to put it on eBay and get another one - but if so what? The Yam YEP201 looks nice but don't think its compensated? 3 valves not a problem as rarely use 4th anyway. Budget is £1k - can push to £1.4k Suggestions?
