That price on eBay looks really reasonable to me. I've ones like this from Curtec for years. The one thing I like is the handle option on mine, makes carrying much easier. But honestly for less than $25 shipped the eBay ones look great.
You can buy the Curtec ones from General Container, but I think they're ~$40 or so. I got mine from a guy on Craigslist in Toledo, but I'm not sure if he still sells them.
