I am planning to get a PS3,
an AV receiver (ONKYO TX-SR605),
a pair of ONIX x-ls speakers,
OPPO DV-980H,
a bigger TV/monitor (probably SHARP or VIZIO) than my current 23" (if my financial situation permits).
For the cable, I need a RCA cable, speaker cables, HDMI cables, component cables.
other than the PS3, I probably would get everything online. Even the PS3, if possible, would be bought from online
