I've actually got 4. They're all packed up in boxes right now, though, because I'm in the middle of moving. It might be a while before I get around to it. I'd have to test which ones work and which ones don't, but I'm sure at least 2 don't. That might not be for a while, though. I'm moved into the new house but everything is still boxed up.
Do you have anything useful for trade?
