For buying domains, I usually rely on Godaddy Auctions -
Code:
https://auctions.godaddy.com/
You can find domains there for pretty cheap price!
You can try also the following -
Code:
http://www.sedo.com/
http://www.namejet.com/
http://www.dnforum.com/
https://www.snapnames.com/
http://www.pool.com/index.aspx
Basically, what I look for in a domain is age and PR which you mentioned as well!
You can check both age and pr through the following -
Code:
http://www.cekpr.com/
http://checkpagerank.net/
Now, let's do some manual work -
Search for the following terms in Google -
Code:
info:domain.com
site:domain.com
If both of them returns the domain in result, than the domain has legit PR.
For age -
Code:
who.is
http://www.samswhois.com/
You can check the registration date of the domain on these 2 sites and be sure about the age.
If you are not comfortable with buying domains, which may cost a lot of money and time of negotiation, I suggest you to use some drop catching tools like -
Code:
www.dropking.com
http://www.domainafterlife.com/category/drop-catching/
What they do is, when a certain domain is dropped aka deleted, these tools register that domain within seconds before anyone else register that domain! Though, do not expect to register those PR8 or LLL.com domains! The pros will beat you up in no time!
You can find which domains are gonna drop from here -

Hope that helps
