Jesus!!! no kidding? you have a problem, mate...
I sometimes regret paying for a couple of the subscriptions, but you pretty much answered it yourself - exclusive content sometimes stays that way.
Hell, a couple of the ones I signed to are amateurs with their hubbies doing the webmastering. Not much chance of finding their stuff around.
Factor in ease of use, the large amount of content with some of the larger sites, and the fact I feel like I'm giving back by supporting them, I don't feel too bad about it.
