A first machine is usually a choice between convenience and a 58 mm basket, not between two identical boxes.
Start with the drink, not the badge
If you want milk drinks on weekday mornings and you do not want to learn temperature surfing, a fast thermoblock with automatic steam is a different product from a single-boiler Gaggia. The Beginner Friendly score on this site is that difference, written as a formula. It is not a claim that one coffee tastes better.
The Dedica is the cheap, slim end of the catalog. Most of its specs are unverified in this dataset, and the page says so. Use it as a budget marker, then confirm the current US model’s portafilter and tank on De’Longhi’s site before you buy.
The Bambino Plus is the one in this set with a manufacturer booklet behind the 54 mm portafilter, the 3-second ThermoJet heat-up, the 1.9 L tank, PID, and hands-free steam. It does not grind. Budget for a grinder or the setup is a tamper and a bag of preground coffee, which fights the machine.
The Classic Pro E24 is the 58 mm single boiler with a brass boiler on Gaggia’s North America page, and no PID listed there. It asks more of you. It also takes the same baskets as a lot of prosumer machines, which is why people keep it.
What $500 means here
The under-$500 list uses the prices on file. Those prices are sample unless a row says verified. Treat the cutoff as a sorting aid, then check the shop.
Machines with a built-in grinder, like the Barista Express, solve a different problem: one box instead of two. The built-in grinder is not scored as if it were a Niche or a Specialita.
