Poker video subscriptions

[Toronto86er]

Not really sure where to post this so I'm sorry if it's in the wrong forum.

I'm a solid, winning player but am looking to really go for a push and possibly move up in stakes soon and was thinking about getting a subscription to one of the video sites (cardrunners, stoxpoker, etc).

Does anyone have any experience with these sites and can compare the better ones for me? Do videos have a 'per-video' cost or is it unlimited access? How much per video? Can I keep the bought/downloaded videos on my PC for later use? etc etc

I'm a NL tourney player but am delving into FL rings a lot more, as well as a little bit of razz and OH side games. Another thing to note is that my bankroll is standing at around $1200 - is it even worth it for me to get a subscription at this point with my budget?
