My first espresso machine was the Starbucks Barista espresso machine. It uses a pressurized portafilter which allows you to use a coarser espresso grind. For years, I used the Starbucks Barista Grinder with this machine and it worked wonderfully.
I just grabbed one of these for $5 used, but it looks brand new. I have not plugged it in yet, bought it off the electronic sale board at work. Lady I bought it from says she got it a garage sale and never used it so there is a good chance it was never used.
