Thank you for your response.
When I got my Zoom R8, I found myself comparing the design to the Roland VS series. Obviously the Rolands are much older but Zoom is far superior in how they lay things out. Zoom's mobile equipment is impressive and offers quite a pallet.
Since this is for installation in my church, I would prefer a rackmount unit which won't walk away. But the U-44 is $140 while the Focusrite 18i20 is $500.
