For group builds I have become fond of Allene's Tacky Glue....and recently discovered Allene's Turbo Tacky Glue. It's a little thinner but dries more quickly (hence the "turbo" in the name). And yet it doesn't grab a motor mount going in at the wrong time like yellow wood glues.

I hear you on epoxy. I have not reached that point, but I don't use it unless I must (motor retainers on larger models is about the only place in rockets where I use it).
