I'm currently using a 6-space (vertical) with slant top. It's a bit large. I'm wanting a shallow case to house my power regulator (3 spaces), compressor and wireless. I think it might be easier to wire my yammy mixer each week than the way I'm doing it now, which is to put the power regulator on the floor. On the case, I'm kinda partical to one of the lighter Gator cases. The SKB thicker plastic units are a bit too heavy/bulky. Wouldn't mind a wood case, as long as it's solid.
