I get compulsive. I research, learn, and spend. This espresso thing has all the earmarks of another, "Honey, remember that obsession you had 3 years ago for xxxxx? Now what are you getting into?" conversation.
You *should* be scared! I am also a serial compulsive, as I'd guess many others here are. I used to just like coffee...
What separates this compulsion from some of my others is that I drink coffee every day, but don't have a daily urge to build some furniture, or rearrange the aquarium, or brew some beer, or make some wine or mead or a traditional Diane sauce, or catch a few stripers, or, or, or... So I tend to stick with this one.
My only advice is that once you start, make it a point to try to isolate one variable at a time and go about it in a methodical way. Dose of coffee, distribution of coffee, tamping style, brew temperature and roast profile (yes, you will come to insist on home roasting...) all affect the final result in profound ways. I wish I had been more methodical when I started, but in my ignorance I took the shotgun approach and only recently (after two years or so of flailing around) have begun to really understand what is necessary to get good, repeatable results.
Good luck, it's a lot of fun.
