i've learned a lot in only one day's worth of reading many of the posts here, but wonder specifically about buying an at-home espresso machine in starbucks - is it worth it? how can i simply make a great cup of coffee or espresso at home? my senseo is not doing the trick! i have for years just been drinking coffee, refusing to believe that it makes a difference where you get it - but now i am starting to see the light! this crap at home is just that! it seems (from what i've read here) that maybe i should start with a french press before investing in a more costly machine - but when i do make that investment - where do i turn? thanks so much!
