I like them but I find the espresso a bit harsher than even one coming from a low end (200£ budget) espresso maker.
BTW just to answer seriously to the OP, first question you should be asking yourself is do you have a decent grinder (ie no 10£ blade Tesco grinder) but a good proper burr grinder. If you don't up your budget by at least another 100£ and look for something like this Iberital MC2
Then any of the above mentioned machines will give you a decent espresso once you get the hang of them.
Also the grinder is a good investment for any type of coffee you want to make. Properly ground coffee is the second most important thing for making a good cup of coffee. The first of course is freshly roasted whole beans.
