Breville VCF149 Bijou Espresso Coffee Machine, Automatic & Manual Espresso, Cappuccino & Latte Maker, 15 Bar Pump (Silver) - £99.99 @ Amazon

If you want good espresso at least equivalent to what you might buy at a cafe, then the consensus seems to be that you need to spend a bit more on a machine. The Sage Duo Temp, and Bambino models are well regarded at the price and work well out of the box. The Gaggia classic is well regarded, solid and has better parts availability but might be a bit more faffy to get consistently good coffee. You will then need to get a grinder that can go fine enough for espresso. The two Sage grinders the "Dose control pro" and the "Smart" are well regarded at the "budget" end of the market. Together you are looking at around £500-600 new or around £300 second hand for the coffee machine and grinder. Which is similar to the entry level Sage Barista unit that combines a capable grinder and coffee machine in one unit.

Personally, I have the Sage Duo Temp Pro and their "smart" grinder and the espresso exceeds what I have had out 95% of the time.

If you prefer longer coffees, then an Aeropresse, Mokka pot, V60, or even a cafeteria combined with a cheaper burr grinder are capable of producing equally good results. The big thing is to grind the beans fresh, as the taste of ground coffee deteriorates very quickly with a noticeable difference even after 24 hours.

Don't know how good this is, but on the surface it's a great price for a starting machine
