Yep, still have the blue box. Works fine mostly, I don't rev the thing very high. Mine got a little warm once or twice, the epoxy on the back of the box melted a little and dripped down the fender apron. (see pic)
Never bothered to diagnose it though so I can't say why it got hot - likely unwanted resistance somewhere. Seems OK now though, no more melting has occured, it's been that way for years.
