consider subscribing to a poker training site? And if so which one?

im currently an average winning player at 100nl full ring where ive worked my way up from 5 buck sngs and 10nl. Yet i really want to take my game to the next level by seeing how top class players play and the thinking thats involved with that. Thus i think suscribing to a site would be a good idea.

So what do you guys think specially anyone who has a subscription themselves.
