getting prints done over the internet in Holland

I've finally decided to try to get some of my photos printed.  A couple years ago I did it over the internet in Denmark, and the results were great.

Does anyone happen to have any tips for doing this, and/or any good sites that deliver good quality prints?  I live in Holland, so Dutch companies would be good, but I guess shipping isn't much extra around Europe.

Any pointers would be much appreciated.  :-)
