There's also http://opensteetmap.gryph.de/bigmap.cgi which again 
requires you to input tile coordinates (or paste any tile URL into the 
"Advanced" box to start). Then you get a map tile display and a menu 
that allows you to shrink/expand the selection. (There's also a hidden 
feature where you can add a "scale=nnn" parameter to the URL and it will 
re-scale all tiles to a width of nnn pixels, to give you better overview 
over large areas). When finished, you can either print from your browser 
or download a perl script that will then download all tiles and make one 
giant PNG from them.

I regularly use that to create 8000x5000 PNGs for poster printing, and 
the CGI source is of course available for everyone who wants to improve it.

Bye
Frederik
