Any good armory/lobby missions?

[thirith 27]

I'm looking for an armory/'lobby' mission - something that allows us to wait for players in-game, test ACRE and faff about with weapons and vehicles before the actual mission begins. Nothing overly fancy, no need for mission objectives or the like, just something like 16 available slots so people can meet up in-game and wait for the others.

I've heard good things about ARMEX and Losis, though I don't know how they compare or whether they're the right missions for this kind of thing.

Any suggestions would be very welcome!
