I've had half a dozen Uke's over the (30ish)years and only ever broken two strings and probably only done a complete re-string four or five times. Uke's hate new strings - the older the better for me - if you want bright, get a banjo;-)
Anyways - popped into a music shop whilst shopping for the lad's school shoes and picked up a set of buffed black Uke strings for £4. Gets home, and they're double length, for a baritone. Two for one. Nice.
Ukulele Rip-off Expose. For each and every £5 in the minus from a £50 one that you spend - the intonation will be one mil out - even when measured over three models by the same maker (rhymes with Ashton;-)). That can't be a mistake.
