I've had a similar path. The b9.1 was brilliant! but, just way too big so i built up a mini pedal board to do the same job that i needed it for. I've since went through an ms60b, b3 and now with a b3n. Been happy with them all.
I must admit, i think the b3n has nailed it when it comes to functionality. I really can't see the need for touch screens or even a large lcd. Maybe on the more luxurious models like the helix it makes sense, you're paying money for a premium product. but, for the zoom level product, id rather the money go into durability and sound.
That finish looks naff too
