Yeah, I kinda felt like the Joker typing that last bit...

So I stumbled upon a working black Model M keyboard by IBM. All 'clicky' and everything. Works great, has a built in mouse nubbin... checked on eBay and found a ton of various Model Ms going for various amounts, anywhere from $10 to $200.

does anyone know a guide to these things and if/why they would carry value. I like my dual-wireless Logitech combo so I'm in no mood to change but if I have something worth even $20 I could use the cash.

Plus, I really want to know why. Personal preference? Those clicks are kind of annoying.
