Well welcome back to the site and hobby!
I've had good luck over the years with ebay but others haven't. You can always ask the seller for a reason why they are selling it. Maybe they just did an LED upgrade and the thing is all but new. Then again, maybe it does the same thing yours does.
If you aren't comfortable with it you could check out
Mediabaskets.com They have replacement part for $109 new. (I think it's the right part but better double check)
