@everettpsycho from my research, I'd be looking at the Bambino or Infuser, and only get the Barista Express if the price is the same/better as those two. I haven't seen anything to indicate extra performance over the other two, just the built-in grinder. IMO the next step up performance-wise in the Breville lineup from the Infuser would be the Dual-Boiler, ignoring the consumer friendly "Touch" machines.
I can recommend the Infuser if you can get it on sale for $500 (what I paid for mine) or less and it comes with both the pressurized and non-pressurized baskets. Performance with the Bambino seems to be on-par, but it sounds like the Infuser is better for polishing your barista skills with manual controls for the steam wand and a dedicated hot-water dispenser.
