Collecting reciprocal links

So how do you get reciprocal links? There are several ways and both have good and

 bad points. Of course, the tried and tested method is to simply do a search using

 your favorite search engine and email the webmaster of every site listed

 in the top 20 or top 50 But before you do, add THEIR link to your page first,

 or they won't even consider your request for a reciprocal link.
