I need a new Mac keyboard

I need recommendations for a good Mac keyboard. I’ve about had it with the standard-issue Apple model I purchased along with the new monitor. Anyone who thinks this is a good keyboard has never typed on a good keyboard. Period. Every time I use this thing for more than 5-10 minutes my fingers start to hurt. I constantly feel like I’m pressing the keys harder than I should have to — they’re much too mushy. It’s very tiring. The only thing I can say I really like about it are the USB slots on the back, but a lot of keyboards come with these now.

My favorite keyboard of all time would have to be the black Keytronic Lifetime Series model I bought ~10 years ago. My dad is still using that very keyboard, and, somewhat suprisingly, the company stillsells it (search the page for lt_designer). If I wasn’t looking for a Mac-centric keyboard, I would buy another Keytronic this very second.

Of the very limited number of made-for-Mac keyboards available, I’ve currently got my eye on the Matias Tactile Pro ($150!), the macally iceKey, and the Happy Hacking Keyboard Lite 2 (you can’t beat its [non-]footprint). I’m leaning toward the Matias model because I’m partial to mechanical key switches and I know that that one has a nice clickety-clack feel to it.

If you’ve used any of these before and have an opinion, please let me know.
