I have a Classic, but I have added a PID to it, and some other things to make it easier to pull a good shot. I bought my Classic from ebay, but it did need some work when I got it, it was pretty old, and full of scale. If you handy, they are fairly easy to work on, and take apart.
The Coffee and Espresso lack the 3-way, but have the same boiler, group, and pump, so are also worth considering; the coffee they produce is indistinguishable from the Baby and Classic. However, the Baby is usually available somewhere refurbed (
not used!) for under $300, and the 3-way helps keep the machine clean, so it is the machine I'd recommend.
I think the grinder class considered the bare minimum includes the Nemox Lux, and some of the Ascaso, the Vaneli mini pro II and II and a couple Lelit grinders.
The Gaggia MDF is also a fine starter grinder, I think better than the small conicals, thought the steps are large.
Most of our drinks will be milk based drinks; is the lack of a heat exchanger or double boiler (whatever those are) going to make back-to-back drink making difficult?
For multiple simultaneous drinks in a single-boiler machine (ie, two or three lattes at once) you will need to brew all the shots first, then steam all the milk. For back-to-back drinks, you just have to wait until the boiler cools back down to espresso temp. This is a matter of minutes on the Gaggias, is the one big advantage of the relatively small Gaggia boilers.
