Link Trading Q

[Linkster]

Ill stick my neck out a little here - first off - remember that you really have no way of measuring what the PR is of the page linking to you as Google has officially removed any way of really seeing that - the toolbar PR is definitely not correct and the only other way of measuring it is very time-consuming (although some of us still do it)
Now lets talk about a seperate subject - Page Rank - not to be confused with PR - if you see that a page (category in this case) is ranking well in the SE positions (SERPs) in Google, then it is probably a safe bet that you would want a link from the category with a good mix of text in the link if you can get it for your "theme"

On the other hand if you can find a "niche" index page that has a good ranking and seems to be legit, then that would be a better link, if you can see that that page is affecting other peoples site in a beneficial way.
