Spark fun has a few products that you can use as-is (no schematics):

Usually I just go to national semiconductor and use their power designer:
http://www.national.com/appinfo/power/webench.html
You put in your input voltage range, output voltage and current, and
it spits out a design. If it's a generic enough design you can even
order kits from them.

It gives you a good starting point, although all these places (linear,
maxim, etc) will have data sheets with good regulator designs using
their parts.

There have also been other cheap regulator designs posted to the
piclist - do a search.
