Thanks for the replies. I want to know if it's going to be better to work on an EMD domain, or picking up a domain with some PR2-3, for my site what are your opinions on this? I only have one competitor in Google for my niche who has a completely irrelevant domain name for that niche and still ranks for it, despite not having great back links but is PR2.
What I plan on doing is creating better content than him and more so I'm not sure if an EMD domain will be good with 0 PR or should I try and grab a high PR domain.
