Zoom is absolutely killing it these days. The MS-70CDR is exactly what you need for your board. It's got any delay or reverb you could want (from the classics all the way to the exotic sounds). Screen is bright and beautiful, navigation is easy, and the four directional buttons are actually pretty handy if you need to make some quick moves at a gig. This one is fairly new, got it a few months ago, and it's been kept in a clean, smoke free/pet free environment.
