Well, don't think anyone here can help much with what you've given us to go on. Little things like price, size, condition, make a lot of difference. But, even with what you've told us, I can give you one piece of advice. Don't sweat it. If you like the way it looks, feels, sounds, and don't see any obvious damage on it, then buy it. Of course, look on eBay completed sales, and at listings on Reverb to get an idea of prices. You're buying a Ukulele, not an antique. So don't over pay. Now here's the advice part: You buy this and live with it for a while. If you like playing the Ukulele, you will buy LOTS of them in the years to come. So, this first purchase is not such a big deal. If you don't like playing the Ukulele, then keep it, give it away, sell it, whatever. You've tried it out and don't like it. And that's OK too.
