Guys, he's asking for 84 key. I'm pretty sure Filco doesn't make anything of that form factor. On the other hand, the Keycool 84 fits your needs exactly and has nice medium-thick PBT caps, much better than the thin ABS on most (Filco included), and they are lasered, I believe, so they shouldn't fade at all. I don't know if it has DIP switches (probably doesn't), but you can do the more annoying solution and autohotkey it.
As far as your switch choice, seeing as you play lots of MMOs, Reds are traditionally the way to go on those and they are comfortable for lots of repetitive pressing.
