I would + the idea of spending what you can on it, as a cheap one will make you grit your teeth if you get into it. That said- I probably could have been fine forever once I figured out how to set-up my Makala's correctly if I was not the kind of guy that belongs on "Hoarders". Totally a staunch member of the "one of each" (or two...or three) club, except concert.
It is not that I have not played concerts and loved them, I just played one I loved way too much and now the rest will not due, so I save the pennies for it (It was a Ko'Aloha). Concert is (to me) perfect size for all-around playing (or super-soprano) because I like the neck length when it gets real and I have to really get some wild chords going. But, as you have found, ask a simple question and get 700 different answers, because we all like what we like. My collection, for instance, has a lot more Spruce than Mahogany in it (and no Koa...yet).
I would say play around with a few if you can, and take all these folks recommendations into account...and seriously look long and hard at the Ohana CK70RB in the marketplace. Really cool tone, good volume, great price. If I did not love the Ko'Aloha so much, I figure I would be buying it right now just to round things out around here.
Oh yes- I also concur with setup- this is a must for beginners know one wants you to know.
