If buying new, the minimum cost of admission for "real espresso" is somewhere in the vicinity of $1000 for a grinder, espresso machine, and the necessary accessories. Assuming your purchases are well chosen, the more you spend the more consistent and easier to use your equipment will be.
The most common type of inexpensive machine is what's called a "single boiler, dual purpose." The good ones do an adequate job of espresso -- with occasional forays into the very good; and they're also okay at steaming small amounts of milk for one or two cappuccinos -- but they do a piss poor job of steaming milk for multiple drinks and even one large one may be too much if you want quality milk.
SBDPs are the way many people start in quality home espresso brewing, but if you can afford it I think it's worthwhile to spend an extra few hundred on what's called an HX (heat exchanger) machine. Not only are they (almost always) capable of doing far better with milk; they're also (almost always) a lot easier to consistently dial in.
There are other choices as well.
Espresso machines are very expensive, for sure. But the real sticker shock for most people is the comes with the cost of an adequate grinder. It's easy to think of the grinder as an accessory, rather than a co-equal partner of the brewing chain -- but that woefully underrates its importance. Good grinders are expensive, no two ways about it. $200 will get you a barely adequate grinder. Take a deep breath and think of $400 as a minimum to step up to decent.
As with many crafts one of the highest hurdles every beginner faces is determining what his actual goals are. Then, if the budget is there, it's fairly easy to match the equipment to them -- God knows you'll get plenty of advice. Another thing common to many crafts -- so called "entry level" equipment, the sort marketed for beginners is the most difficult to master and will produce the most inconsistent results.
Think of it as being something like optics -- no matter how good your eye, or how carefully you focus, you can't get sharp images from bad lenses. Photography is a good analogy because one of the goals of choosing and making coffee is revealing all the preferred nuances in the beans.
A reasonably skilled home barista, using decent equipment and good beans, can do much better at home than all but the very best espresso specialty stores. Given those good beans, and that threshold level of equipment, it's more about attention to detail than anything else.
Hope this helps,
