Another option and a good first sour beer is to consider a Berliner Weiss. Since they (generally) just use Lacto for souring, they're done in weeks instead of a year or more. Also a great refreshing beer for summer.

The newest Brew Your Own 250 Clone recipes has their recipe for La Roja- check it out.  After it has set in the fermenter for about a month rack it into secondary and throw another batch on the yeast cake and bugs.  You could probably do this for as much sour red as you want.  The Mad Fermentor blog mentioned earlier has some good stuff going on.
