I used to have that exact machine. It got clogged and rusted inside. I've got the newer version of it now, and it can be temperamental at times. I have to run a clean cycle every couple of weeks to keep it in tune. It does work really well though, and cost me about $500.

I once managed to do this with it:

Do you want to make the coffee from scratch, or do you want the machine to make it for you? $1000 will get you a pretty good one-button automatic machine, or a really good manual machine.

If you're getting ground coffee, make sure it's not ground too coarsely. If you have a good grinder, go to a cafe and try their coffee out, and if you like it and they sell beans, get from there. The beans you buy do make a lot of difference, and having a good cup at a cafe gives you something to try to replicate at home with the same beans. I'm still working on it...
