Keyboard/mouse that won't destroy hands?

This summer I developed tendonitis. Now, because I've been typing thousands of words a day, my index finger is stiff and store. I suspect it's due to unresponsive keys. My Mouse 1 button is also broken.

Now that I need to replace both these, I'd like to replace them with something better. I never used and of their extra buttons or features, they just collected dust. All I need is the standard. Quietness might be nice, but above all I want them to be comfortable and (relatively) healthy. Is there anything available? Everyone talks about the IBM springboard, but that sounds like it would kill my fingertips.

Get a decent, oldschool IBM (or IBM-like, as in, massive, sturdy, resists a nuclear meltdown) buckling spring keyboard. It's the best keyboard ever, anything multimedia is shit, anything with power keys is shit, anything with alternate layouts is shit, anything with shitty shaped keys is shit, anything with missing keys is shit, anything split is shit, anything that is not IBM-like is shit.
