I really can't answer that question well, but I can point you to a forum...http://www.home-barista.com/forums/
I have this machine:http://www.wholelattelove.com/products/expobar-brewtus-iv-with-vibration-pump
and this grinder:http://www.wholelattelove.com/products/ ... ee-grinder
So I have about $2500 in it all with the latest upgrades. I'm 100% self-taught on espresso brewing and this combination has been making fantastic espresso from the first shot I tried, except for a period when I let it get dirty. I've had it about 3 years and I only really cleaned it twice. I should do it every 6 months or so. It didn't really start producing substandard coffee until about a month ago. With the latest upgrades, I can easily say that this is making the best coffee I have ever had - and that's after seeking out the supposedly best coffeehouse in London, NYC, and Chicago. That's obviously subjective, but I honestly don't think I've had better. I'm achieving this with a rather ordinary supply of coffee. I'm going to order my favorite beans and am anxiously awaiting the result of great beans with my current installation.
It's maybe a lot, but it's saved me quite a bit from buying espresso on the street.
I rarely buy it in restaurants or shops, because it's always a disappointment since I now know what it should taste like.
If you force me to guess, I would say that you could come close to where I am for $1500 +/- $250.
Hope that helps.
