I've got a like new Kala Longneck Soprano Sprucetop Flamed Maple uke for $150 plus $15 shipping. It includes a nice Stagg tweed case and a soft gigbag. PM me if your'e interested. I take paypal and will ship it UPS to you.
That Kala looks like a good deal. There's also the fleamarketmusic.com marketplace where you can usually find a preowned Fluke or Flea for about $150. You should have no trouble finding a great uke for that price.
