Well, imho, the K10 is going to have the most consistency hands down, BUT, the K10 also has more grinds retention and you may end up wasting a larger percentage of your coffee purging out old grounds. If you were to single dose with the K10, you could get every shot out of that bag with practically zero waste. The K10 is more work to use. You should realize that you'll sacrifice one of two things with the K10, time or coffee. With the K30 - if you use 1 coffee at a time, you'll only be bothered when you get to the end of each bag. If you only buy 12oz at a time, and switch coffee every go - the K30 will need a couple shots in the beginning as well to calibrate it. Think about your consumption rates as well - how long does a 12oz bag last? This will impact what is happening to the beans in the hopper. Are you good to throw a half bag of beans in the hopper at time? Anyhow - there's some food for thought. It's a fork in the road in some ways as to how you will prepare your espresso daily, so take some time and choose the right path. It's a big purchase.
Sidenote - as a home roaster, I am constantly tasting new roasts, new beans, blah blah. If you think someday you might open that can of worms, I'd say the K10 would be helpful.
