ninremix asked a reasonable question and there is no need to trash him for it. I understand the cafe mentality and agree this is the best site for fantasy baseball information, and you can't beat the cost. But there are plenty of pay sites out there some with very valuable information, and it seems reasonable to answer his question.
I'm no expert on what is out there, but I'll give a couple I have heard of.
It seems lots of folks like baseballhq.com. It is very pricey, and they have a very strong focus on the numbers. It isn't worth it to me, but I know it is well respected.http://baseballprospectus.com/
is another one that seems well respected.
Another great resource is http://www.fantasybaseballhub.com
. The hub itself is free, but they provide links to all sorts of other services and show which ones are pay services.
