lol few tips for free put your links in the sig here, DP gets crawled alot comment on a few huge blogs, doesnt matter if there do follow or not make an aboutus.org page Post fresh content
Second free advise, just register your site http://www.google.com/webmasters/ You will be indexed in google in about a week, every search engine (Yahoo, MSN etc.) have a similar page, so register.
I agree with pixeladd. Keep your $. Find a legit way (sigs are) to drop you link here at DP. If it wasn't Christmas, I would say 48 hours or less for the bots to show up. Another legit way is to ask for a site review in the correct forum.
you can also post a page of each site to digg.com as long as they meet their requirements, they are almost a 48 hour gurantee.
Buddy, that would be a waste of $5! YOu can do it for free and it's really easy! You can follow these steps here if you want M3rC
