Could you explain what is a cherry or costar stablizer? I'm sorry I'm kind of new to the techinical part of these keyboards. Costar? Cherry? Are they on all keys?
Ok, if it's the "Look" you're after.
Get the quickfire rapid RED + the blank pbt caps.. That case is now almost completely black like the Filco.
Buying a filco is kindof silly these days, cuz the caps arnt' that great vs pbt, and the QFR has the same colors available.
For example, since you already have the MX blue tkl, you could buy the MX Red tkl and just swap the cases..
That way you'll have a black keyboard, and you'll have money left over to buy the PBT keycaps, which are much much better than filco stock.
