We use Hot Wired Content and their products are fantastic. Don't want to mention a price though, as you should talk to Nikki and get a custom quote.
Also using Virtucontent since just recently. Their Porn in Public plugin is a must have
I have seen
http://www.holio.net also has a spring break feed and
http://www.publicnuditycontent.com has some nice looking feeds too. Never used them though.
There is another provider that I know has a spring break feed, but I can't remember wich one right now...
