Ok i'm just starting in this and if someone can point me a resource to jump start me in the field i will really appreciate it.
I want to buy lots of PR, aged domains in various niches for the best possible price.

I've got domainface acc and looking, found quite a bit of great domains, but decided to read a bit first about the possible caveats
