I’d suggest steering clear of the micro Marbles. The urge to go as small as possible to save space is understandable, but some modules lose more in playability through miniaturization than you gain from having the extra space. Marbles is a lot of fun to tweak, but those tiny knobs would very much restrict its playability IMO.

Ahhhh a very good point Skreetis thanks! You are right, from what I have seen so far, Marbles is all about tweaking...so those tiny knobs may get annoying after awhile. I guess Marbles and Elements may be going then :) and if I really want them later someday, I could get the full size versions and put them together in a smaller tabletop case/skiff of some kind.
