Collecting anything is a bottomless pit: I used to only search for my favorite keyboard in the IT support storage room, and after trying out all those IBM keyboards, I picked ONE which was a high quality very smooth rubber dome; though I attempted to start a relationship with a Model M, it didn't last.
Now I foresee I can easily add up to 5 more keyboards to my collection not counting some unreleased ones, while parting with only 1 of them because it cannot be reprogrammed. Not to mention all the customized and artisan key caps I am getting. After all, I need only ONE board.
But I like it if my fingers are not too distracted from their real work.
Good luck for your sale and the Viper!
The b.Face sold is almost exactly how I want to build at 60%, except for my taste of ErgoClear to pair with the clear case.
It's a fantastic board. I hated to part with it, but with the Viper re-releasing soon I'd rather have that and keep the MX 60% collection to just one board.
