One of the founders of the site, Suzanne, tried Nutrisystem and she wrote up a review, which you can find here:

I haven't heard anything about the eDiet's delivery plan.
She also reviewed Diet to Go:

Personally I am too cheap to sign up for one of those plans, although even so I know I spend a good bit of money on food. I don't do much cooking either, but I find ways to get by. I do most of my shopping at Trader Joe's and they have a number of really decent pre-done meals and things. I hope you find something that works for you!
