If you are using one of those Krups blade grinders, almost anything would be an improvement. A Moka Pot uses a fine grind similar in size to espresso. And in order to get a consistent grind of that size, you need to spend some coin. Duffjr mentioned the Baratza Virtuoso. I happen to have one as well but I don't use it for espresso. I only use it for french press. I agree that while Baratzas aren't necessarily the best, they are very serviceable. My motor went on my Virtuoso recently. I emailed Baratza and had an email response within a half hour. I ran some diagnostics based upon the technicians recommendations. Once he determined it was the motor he said he'd send me the motor if I thought I could install it myself. He included a video in his email. After watching the email I thought I could handle it. Within two days I had a new motor. I successfully installed it myself and I'm back up and running. For the OP, really any burr grinder would do a much better job than the Krups blade grinder. And for Torrance, I have found that the best performing grinders end up being more expensive. I can't say this by my own experience but I've read so much literature, posts and blogs about people's experience with different grinders that it is pretty clear that when it comes to coffee grinders, the more you spend, the better the grinder, generally speaking. I doubt you'd find many posts on this site that go in depth into lots of different high end grinders but there are other coffee forums that do. This hobby of ours requires research. The more you read, the more informed you become. Just my two cents.
