I was lucky enough to pick up a reconditioned Rocky Doser grinder (wanted Doserless but can't be too picky) for a good price on ebay last night. I promise to heed the warnings of Vicki's desperately unfortunate experience and try to be much more careful than I usually am. My next step was to order the Gaggia Espresso plus tamper, 12 oz. pitcher, = etc. My question is what coffee should I try first? This is my first experience with a non-toy espresso machine and I've been reading everything I can get my hands on but I know that what I really need is experience pulling shots. I have lots of home-roasted (via bread machine and heat gun) beans to pick from – Sumatra (have Classic but am waiting for a SM shipment of Blue), Monkey Blend, Italian Espresso, and scads and scads more. Should I stick with the typical espresso blends or pick a single variety? I know eventually I'll be trying everything but for this first learning phase does it matter what I use? I'd like to mention that I was so happy to get this grinder. Because of my budget I was all set to get the Gaggia MDF which probably would have been okay. But I was able to get the Rocky for only around $35 more. This increase I was able to talk myself into. My husband's birthday and mine are only two days apart (in March) so this is our birthday present to ourselves. We usually try to buy one thing (electronics typically) that the both of us want. We're both gadget hounds, although I'm the handyman – I mean handyperson :) I'll be the one who uses it the most. Good guy, my husband is. So, what beans should I try first – I need to start roasting 'cause I think I'm going to need a bunch! Oh, we'll probably be doing a mix of espresso and cappuccino.
