HDMI Cables.... many questions...

[Bdogg]

Hey Everyone, I need some advice/help... I just ordered a Onkyo 606 receiver which will call form some a facelift to my setup... I want to use the HDMI from my BD30 blu-ray player, and my DVR. The TV will be about 30 feet away from the reciever using an HDMI cable. Will that work, is there a limit to how far I can go with HDMI? I've looked on Monoprice.com and they list several hdmi cables that are that length.

My next questions is, whats the difference between 1.1 and 1.3 hdmi cables? I have a 1.1 cable from last year and need to order new ones, should I replace the 1.1 or keep that and just order 1.3 for my new cables?

Finally, here are the cables that I am looking at and the price range is so different... almost $30.00 whats the difference between these cables? Thanks, sorry I am new at this part. (eventually the 30' cable will get put in a wall if that matters)
