For any of you who do freelance work besides your own novels, have you used any fee based subscription services and if so, what are your thoughts about them?

The two I know of are which is $50 for 2 years and the AvantGuild membership at MediaBistro for $97 for two years. If you have used either one I’d be interested in hearing about any pros/cons.

And if you know of any others I should be away of, please let me know.
