I love my KoAloha concert presently in low G. Ordered it from MGM last November. Had checked into factory seconds but with all of the stuff included with mine, nice hard shell case, tuner, book - there wasn't much if any difference in the price. And I was able to see the exact ukulele I was getting; it's gorgeous with a curly koa top and staight grained b/s.
Edit: It wasn't my KoAloha concert that I checked for a Factory Seconds comparison. It was my KoAloha soprano. In that case, there wasn't much of a price difference. With a concert there may be more of a price difference, and I agree it would probably be just fine.
