I don't think all the computerized matching on some sites is worth a nickel but a couple of things are worth paying for. One is retaining messages, notes on the guy, etc. The site should hold on to your stuff for at least a year. Obviously, a full profile opportunity to allow you to describe yourself and see how the other guy chooses to describe himself. If the guy is all about physical and offers no insight into who he is, you can move onto the next. Can he spell, construct a sentence, use spell-check, explain himself without it sounding like he is just picking out positive adjectives (everybody has a mother who say's you're great). Lastly, I like to be able to enlarge thumbnail pics to a decent size but I've got crappy eyes. Some free sites have all of this but most do not. The other thing of importance is the popularity of the site and who exactly is attracted to it. If the relevant population is too small, or attracting the wrong guys, it won't do you much good. Can't hurt to try a pay site for a couple of months. You can always drop it if it seems no more useful than a free one you know. But take the time to actually make a good profile or you're doomed to failure.
