I thought I had seen Access bags on Sweetwater but went to find you a link but they have only have guitar and bass versions. They do have Gator and Gretch use bags that are inexpensive and nice for the money (not as protective, of course). Another option might be a polyfoam case.
For what it's worth, I really like the Protec Max bags They are like violin cases, have firm foam and really protect the uke, but are not heavy. I have one for the uke and one for the guitar.
