I got one really cheap used as a back-up a couple years ago. After testing it out it became my main work horse for the majority of my "cover band" gigs. I just run one side into a Schroeder 1212L(4 ohm) and it's plenty loud. I run it with the EQ section disengaged with my active and passive basses and it sounds decent. My only knock is the lack of a ground lift on the DI.
So even though the sky is the limit, there are limits to what we'll call "sky".
