This is the sound bar I am CONSIDERING buying.

Now, my question is if I want to have theater like sound in my living room, do I need the sound bar AND more speakers? because I want the bass, but I don’t know if a sound bar can deliver that.
I wouldn’t mind having two of those very tall speakers sitting beside my TV stand either..

Another question too.
I have a 42” Vizio and the TV looks so small to me, so is going with the 47” going to be a big difference to me? I want to have the best kind of TV picture.

Your opinions about this TV?

Hi, I am shopping for a new TV. I’m looking for a relatively inexpensive 37-42 inch TV that still delivers good quality at 1080p. Here’s a couple I have found.

What are your opinions?

Does anyone know about Rebu-Shop or rebu-shop.com ? Are they legitimate? Anyone done business with them?

Found them on the web recently, electronics web site. They have name brand quality merchandise at some good prices. I’m suspicious of their payment policy which is done by MoneyGram, no checks, credit cards, or other common forms of payment mentioned as acceptable for payment. Everything I’ve looked at on the web site says “added to catalog on April 10, 2007. Does anyone know or have information about this company, so I can find out and feel safe to do business with them.

What do you think about the Samsung NV15 digital camera?

I read about it in a catalog of a local shop, and the price fits my wallet really well. So I want people opinions on this camera.
