There are a few uke companies making vintage style ukes at the moment but the Ohana SK28 is a real stand out for the price. All solid mahogany and based on a 1930's Martin style 2 uke. It has all the bright and lively characteristics of the original Hawaiian ukes. Sure it doesn't have the volume of a Pono Tenor...but if you want an authentic soprano sound...it'll get you there in spades.
$330 with free tuner.
