I've owned a couple of these. They haven't changed the internal design much (if at all) for years. Newer models just have more electronic controls.
While this "no change" can be a good thing, in this case it can also be bad - the thing that will fail, usually in 1-3 years, is the steamer valve. It will begin to leak, and then it drips onto the the control board.
I've had 2 go that way so far.
If you catch it early, before the control board gets fried, you can fix it yourself (search youtube for a tutorial), or you can ship it to a repair shop that will fix it for around $200, shipped. Fixing it yourself is not a walk in the park, but do-able, and enjoyable if you like tinkering.
Having said all that... these things make pretty good Joe - better than your Mr. Coffee, not as good as a real espresso machine - somewhere in between. Espresso and coffee snobs will scoff at you for your love of the stuff from this machine - but for me, the convenience of a super-automatic just can't be beat.
Using good beans is important. I personally am liking the "Espresso Neuvo" from Paradise Roasters ( http://www.paradiseroasters.com/ )
I have recently moved on to a different brand machine (Jura), mostly because it is quieter and (possibly) more reliable. This brand (Saeco) of machine has a loud "click-click, click-click" as it packs the coffee puck, which always annoyed my wife.
A couple good things about this unit over others you might be looking at:
(1) this is a pretty good price for a refurb
(2) the cleanable brew group is very handy
(3) easy to get parts, and requires no special tools to take apart
Not so good things:
(1) the water tank is behind the machine, so it is very hard to add water when this is living under a cupboard - you really have to pull the tank out, fill it, then replace it - perhaps you could find a better "water filler" vessel than I.
(2) design flaw - leaky steamer valve
(3) click-click, click-click
