I am looking at a surround sound system for the first time.

I have just received a quote from a local dealer for the following system. I am interested in if this is a good system for first time.

Marantz SR 4001 receiver
Paradigm Atom Speakers
Paradigm Cinema center channel
Paradigm PDR-8 subwoofer
Paradigm PV60R ceiling surround
Total @$1,500

I am also considering Onkyo TXSR605 receiver and BW 300 series speakers.

Any thoughts or suggestions?
