Ok, I think I've finally found out what I'm doing for my parents surround. I found the speakers they had aren't as great as I thought so here is the set-up.
Already owned:
Panasonic 1080p Plasma 50"
Dish Network HD DVR
Panasonic BluRay
Optimus Pro LX5 (rear sats)
New equipment:
Onkyo TX-SR506 $200
eD A6-5T5 (x3 for mains and center) $270
Dayton SUB-120 $140
Cables from monoprice
So all this new equipment comes in at around $600, anything you guys would suggest for improvements around this price point?
