I bought my first Swiss Micros calc then and have bought several others. I now own (3) DM42 and (1) DM15. While I loved using my HPs in college as a working engineer for the past decade+ I would never go back to the 33s or 35s. The DM42 is simply perfect for me as an EE. Okay, fine... not saying I wouldn't buy a DM35s but the DM42 is a beast and I carry a primary and backup daily for work.

So that I know what to look for should I need to arrange a funeral for them, what should I be on the lookout for with each model?
