I fully agree with the comments above. Reciprocal linking is pretty much useless today.
I have also found that about 99% of the time when you get a request for a reciprocal link, it is a scam. Either the page they are linking from is blocked from search engine access or the links are nofollow. The goal of the scammer is to get a good one-way link from you while providing a useless link in return.
