I went to a beginners ukulele workshop some time ago and got myself a cheapo soprano uke which developed intonation problems and stopped me playing. As the problem was with just one string someone suggested getting new strings. I have done that and it has made a big difference and I feel I am starting to make worthwhile progress. However looking at I feel I should get a better quality instrument as I can tell it's not really all that well made. Worth the money to start with and see how I get on, but not much more.

If I get a new one, my thought is to get a concert uke - or possibly a tenor. I do not want to spend a huge amount, say 50 to 100 GBP (I can't afford much more just now) and there seems to be plenty in that price range.

I am wondering which makers to consider, and I am mainly interested in using it to sing with so also what are the thoughts on concert vs tenor uke.

Guitarists, please don't bother suggesting guitar instead. I've tried guitar three times in the past and never really got on with it and I rather like the uke and I do feel I am making progress.
