Dell seems to have some good pricing on these. I need the 670 for my HD PVR, Plamsa TV, Sound system, DVD player, and PS2 (yeah i know its old). I need the 520 for normal digital tv, dvd, and sound system.

Am I making the correct choice here? I dont want to break the bank on these and can get both for $170 Canadian. (keep that in mind, our prices are generally higher than the states)

Thanks
