Before I found Geekhack, I was content with my Model Ms. (Sure, I had other keyboards, but they were usually system-specific.)
Since finding Geekhack, I ended up with a Model M13 (since sold), an EnduraPro 104 (second set of mouse buttons is dying on it, and the USB cable is bad... grr...), a Scorpius M10, beam springs, and now I'm getting plate springs.
(To be fair, I knew about the M13 and the EnduraPro, I just wasn't motivated to get one until finding Geekhack.)
