I was in your shoes just a couple months ago, stewing whether to join or not. I did, with the intent of just one month. I am now in my 2nd month and likely will not be cancelling for next. The forums go a bit deeper into the concepts of real life experiences and sometimes I'm not there yet but that's the thing, everytime I poke around there I pick up more and more.
The interviews and teleseminars etc. are excellent. There's like dozens. I've loaded them all on my ipod and listen everyday on my commute. Tons of great info, I have some fav interviews, and the Weekly Review with DA and his senior staff gets listened to every Friday on my way to work for my...weekly review. Great prep and pep talk for the process. Try it for one month is my 2 cents...
