i'd check out the sonic sense bags. im not sure if they are tall enough to stand up the minime, but they are sweet bags.
right now i use a single large compartment dat bag from portabrace and i dig it. on the portabrace, again not sure bout standing up the minime, but the bag i have has a velcro pocket to let the cables in, and i could envision the MME on its side adjusting the levels throught the open velcro pocket.
sweet bags, but pricey.
hope this helps,
luke
