delicious links

Hey guys, Was wondering... of all the social bookmark providers (Delicious, Reddit, Google bookmarks etc.) which one is best for getting ranked. I am thinking if page is bookmarked 100 times on delicious or if the same page was bookmarked 100 times in reddit obviously one of them has to...

I need to get 200+ delicious.com and digg.com bookmarks to three of my sites. That is a total of 600 bookmarks. Anyone out there can help me? Give me a time frame and price. Thanks
