I know when I first started I used PUSH (
http://www.push.tv) which was recommended to me through this site. They have a 30 day free trial, where you get your first DVD and all you have to pay is the shipping.
I used it for 6 months, then decided to go it on my own. Who knows though, I may end up going bck to it. Some people like it and some people don't, but I recommend it.
