hey everyone! im thinking of upgrading to a better uke. at the moment ive got a standard size yamaha yu-4. its laminated and im wanting something better. i want a concert and ive been looking at hawaiian brands like kamaka and koaloha but they all seem mega uber doublebackflip expensive. then i saw the pono mango series. i dont mind paying $500 as long as its a good uke (and it comes with a case). any advice or opinions on mangos out there please?
