We never had a keyboard that didn't work after this "refurbishment". Absolutely built like tanks.
So it's weird to see keyboards like the Model M going for $100+. And I agree that they're nice typers. But then again I'm using the same $10 Logitech I bought at Ross (of all places) when I realized I needed a USB keyboard for something 10 years ago. I toss it in the dish washer a couple times a year to clean the cruft out, but other then some faded keys it works "fine".
The only expensive keyboard I've bought was one of those Bluetooth Mac chiclet keyboards and only because I was using my rMBP as a second monitor and needed something a bit closer to type on. It's okay, but I wish sometimes I had bought the $15 bluetooth keyboards I see at Ross every so often.
I would never have dreamed of doing that. :)
