I have a Stern one in Tron (love it) and a Red Tremor in IM... Call me crazy but I prefer the Stern one. The Red Tremor shakes the game too much. I know IM has some of the best shaker integration, but I wish there was a way to tone it down a bit. I had thought the Cointaker one came with adjustments to be lighter, but that must have only been on a earlier revision, because mine didn't have the holes for that.
Yeah, I might actually replace the Red Tremor with a lighter one. But that is just me.
