OK, cool. Yes, a matched pair would certainly be more attractive, but two-for-one ain't bad just to have an extra for trading stock or EBay fodder or something... $75 a pop... If MK-219s are 2/$99, that'd be pretty impressive, too.
I'll have to go to my POB and see if I got that mailing. I get different stuff from GC than other folks do, it seems, or nothing at all.
Thanks for the clarification. The GC Pro Audio newbie I talked to on the phone was totally in the dark about all of this.
