For me it would be the Alesis M-EQ 230. When I bought it it had already been discontinued, so I bought it off eBay. Shorty after I realized why it was discontinued. I can still recall the (physical) pain of trying to move those razor-thin sliders. And once you did get them out of their irritatingly deep detent, the travel was not smooth at all.
