In reply to Milesy: Concentrate on the espresso and don't worry about a machine with the capability to do frothed milk - more to go wrong, costs more etc. Then spend 50 quid on an Aerocino (made by Nespresso, the bas*ards, but at least you don't have to spend the rest of your life paying them hand over fist for their evil little aluminum capsules).
I dislike Nestle with a passion - it's nice coffee but is drawn straight from the devil's teat as far as I am concerned. But I have to admit the Aerocino is a very good bit of kit. Small, silent, easily cleaned, can do hot or cold milk with small or really very good velvety froth - we have given up on the cappuccino maker on our Jura machine and just draw down espressos, and do the milk in the Aerocino - it's quicker, less messy, and nicer. Most mid range espresso machines make reasonable brews - the lower end can be awful - but it costs an lot to get a machine that does generate enough bar to do a good job of the milk.
In addition, the Aeropress IMHO gives the best non-powered coffee and can go camping easily, so the aeropress/aerocino (no relation) combo gives fantastic coffee if you are staying in a cottage somewhere etc.
