I had a set of Peluso CEMC6 for a while. Nothing wrong with them, it just wasn't my flavor of choice. The cap that makes the Peluso really shine seems to be the Subcard cap. If you can buy a pair with the subcard caps alone, instead of buying the bodies with card caps, and then paying extra for the subcards, that would be great. I think people have worked that deal with Soundpure in the past, even though it's not something they advertise.
I can't comment on the KSM141... I don't think I've ever heard a tape made with them.
In that same price range, consider AKG391's, and Busman.
The best way to choose is by spending several evenings listening to samples on the archive and decide what YOU like. Asking our opinion on mic flavor is like asking us what kind of ice cream to buy. It's your money, best if you decide what you like.
