Makai ukuleles seem to be strikingly similar to other ukuleles such as Hilo and Ohana. As I write, there's a Makai concert and a Hilo concert on eBay. The only difference I can spot is that the Makai is more than $20 more expensive (both are 'Buy It Now's). So it's definitely worth you checking out the Hilos before you buy a Makai.
