Model M was buckling spring IIRC. The Cherry blue switches are most similar to the buckling spring feel, and are about as loud although not quite. Model M's are nice but some people avoid them b/c of aesthetics or because they prefer cherry switches over springs etc etc, many reasons.
I will say that I use a Das and since you are already looking into one, I can vouch that it is a fine keyboard. Immensely satisfied with it (cherry blues).
Thanks for the reply. Where did you get your Das? On their website they are $130, I was hoping there would be a retailer that has them for cheaper.
