I have used many of the ones mentioned, all have good recipes and ratings systems. However, the first one I usually go to is cooksillustrated.com. This is the companion website to the magazine, to which I used to have a subscription. The website membership fee is - I believe - $24.99 per year, which gives you access to all of the magazine archives. I have made many of their recipes, and they are just perfect. Tomorrow I will be making their Eggplant Parmesan again, which is simply to die for. I don't think the website membership costs much more than the magazine, and it doesn't clutter up my house.
Americastestkitchen.com, the companion website to their PBS series, is free though you have to register. After the season is over, those recipes go to cooksillustrated.com.
