Looking for a concert uke in the middle range. I have heard great things about Ponos, mainlands, some Kalas, etc. Let me know if you have something you are willing to part with or something you don't play anymore, I'll give it some new found love.
Some nice concert neck sopranos out there too. $200 at low end of mid-range. Should be able to get a decent solid topped instrument made by Kala, Ohana. Going to have a hard time getting a Mainland or Pono for that price or less.
If you don't require a pickup, here's a deal you won't beat anytime soon. A Kala all solid mahogany concert for $139 with free shipping. May or may not require a little setup work. Has tortoise binding, bone nut and saddle, and it's all solid. I have a tenor with a pickup I bought for just $20 more.
