Hi:

Does anyone have an opinion on Penta 1s vs 2 and 3s?

I've always wanted  pair and there maybe an opportunity to pick up a pair of Penta 1s. I'm reluctant to jump on them because they do not have the alpha numeric display which I think looks "cooler."

 Aside from this were there any other differences? Can the 1s be "upgraded" with newer displays? Also what is the best way to address the midrange foam rot?

Thanks,

Derek
