I'd be a bit leery. First off, there's no real good description if this includes the JS AND Throttle, or if it's just the JS.
Also, X52's (while in my opinion a fine joystick) tend to be a bit flaky. I've heard of too many complain about problems right out of the box. It seems that if you get a good one it works fine during its life, but I've heard of too many LED's not working, or intermittent connection problems, jumpy rudder POT, etc.. etc..
With something like this, you never really know until it's too late.
The starting bid might only be $10, but by the time bidding gets higher in 7 days, it might be approaching the price of a refurbished unit that comes with a factory warranty! You can find this usually for $70-80 if you look hard enough for it.
