Heho!
Prices start like $15 for a "fake" flat free, where only the first 1GB of transfer is free.
The real DSL flatrate is about $30 including the $5 for the DSL line. You have to add the price for the phone line: either analog (about $12-15) or ISDN (about $25-$30). There usually is a initial setup fee about $50 - $100.
In Hamburg where I live there are also other offers available, but it comes usually down to prices between $50 - $80 per month, including phone service and DSL and including a real flat free internet.
VAT in Germany is 16%. Important to know is, that every price you see in advertisings or shops is ALWAYS including the VAT. So are my above examples. Consumer/private clients always see final/total prices. But in general you are rigth, everything is a bit more expensive in Europe, especially common goods, groceries and clothes. However, the us$ is doing very well at the moment and so things are cheaper for you than they used to be in the last few years.
You'll be shocked about gas prices in Europe...
