New Speakers - Which way to go

[MrRoy]

Currently I am selling my Sony HTIB and that leaves me with 3 Yamaha 125 front speakers (center/right/left) and my Onkyo 605. I was thinking about going either of 2 ways:

1. Purchase the 2 remaining Yamaha floor standing speakers and a subwoofer

or

2. Purchase 2 Polk R50's, a CS1 center and have no subwoofer for the time being. Use 2 yamaha speakers for the rest of the surround.

Both can be done for about the same price, but not having a subwoofer in scenrio 2 has me concerned. (I like the polk idea )

Any input or help evaluating both is appreciated.

Thanks!
