Go to Audioholics.com. They have a store. The store currently has an EMP Tek speakers 5.0 setup for $200. Buy this setup. If they are out of stock go to the internet and look for EMP Tek. There are a couple of other dealers with the same price. This has free shipping, so no additional cost. It is actually 5 center channel speakers but you place four of them vertically on stands for your fronts and surrounds. Go to www.thespeakercompany.com
for your subwoofer. They have a 10" sub for $150 that will more than satisfy your needs. Again, free shipping. I would buy the entry level Onkyo or Denon receiver. Either one will do the job well. That should be about $200 +/-. Go to www.monoprice.com
for your speaker, subwoofer, and HDMI cables. They also have really inexpensive wall mounts for your television if you want to go that way. I would get the Panasonic DMP-BD60K Blu-ray player, you can pick one up for under $150. Total you are looking right around $750 including cables. This will blow away any HTIB system. Good Luck.
