Depends on the brands and if they were new or used.
Local 'luthiers' or simply ukulele makers sometimes sell their projects at the swap meet.
Some are good, some, not so good.
Sometimes you can get a very good uke, but most times, well, they're savvy, you know.
They will probably know what they have and what it's worth.
That being said, if you're not too fussy, you can get some imports (laminates) for a pretty
good price. You may not recognize the name brand, but if you have a chance to play them
and they sound good to you....
NOTE some of these are fairly INconsistent in build and finish so please try several to find
the one that looks and sounds good to you.
That being said, Caveat Emptor (let the buyer beware)
Good Guys in Kapahulu about .5 to 1.0 miles from Waikiki is a good, reputable place and being
away from Waikiki, can be a bit less expensive than shops in Waikiki - just because.
It's fun to look, but difficult to find a really good deal. (unless you're not picky).
keep uke'in', and hopin' and searchin'...,
