I think this is a really nice little uke, and at a very good price. I went through the same process of looking at online reviews a while back, when my grandson (11) wanted a soprano with "more frets". The reviews seemed to be unusually good for this one, so I bought it, and couldn't be happier with it. Not only nicely built with good sound, but really looks classy with the high gloss finish. (I have mixed feelings about gloss finishes, as it does affect the sound, but nevertheless, was very happy with this one and it has the look and feel of a much pricier uke). So I think you made a good choice, there's not anything I've seen or heard to gripe about.
It has the added bonus of a little extra room for adult fingers...even on lower frets I have some hassles cramming fingers in for some chords on sopranos, let alone as you move up the neck.
I did see somewhere that it said soprano gig bags will fit, but none of the ones I had would, with the longer neck. I did get the Lanikai floral print soprano bag later, which along with the tribal print are my favorites, and it does fit fine.
Austin Bazaar sells a lot on ebay, and has been around a while, so I'm sure your fine there. There's a lot of pressure in these forums to buy from certain dealers, or perhaps locally, but we can't all buy from the same people or there won't be any competition. I bought mine from Honolulu Music Supply, and it was neat having it arrive and my grandson seeing the "from Hawaii" on the box, but I buy from lots of different places, wherever I decide looks like the best overall deal, all things considered.
Enjoy your new uke; I can't think of a better soprano anywhere near that price range that I'd have picked; my grandson loves it (and he uses most of the long neck too), and when I can get my hands on it I enjoy playing it too.
