Onkyo HTS 5300 vs Samsung HW-C450 Soundbar

[The_Donster]

Man, I feel like I've been doing nothing but asking for advice lately. Luckily you guys seem a bit more experienced in this stuff than I am. So here I am asking for a bit more advice. We're in the final stages of picking out a new flatscreen for the living room, which means we'll be looking to upgrade the sound system and dvd player along with the 13.5 year old set. The room is fairly open, so my wife is a little concerned about shelling out for a sound system that might get lost because of it. She is actually thinking soundbar, since we have one hooked up to the 47" Vizio, but I'm not so sure. On one hand I would have to hire someone to set up things, on the other I wouldn't have to and it would have less wires to conceal. Does anyone have any thoughts on the subject?
