A lot of things pop up here. I don’t have an itemized list of what you are spending $200.00/mo on. You need to clearly and concisely write down what you have, how it is connected, what it costs and what you want your systems do and how. You may/may not get good help from your Best Buy/Circuit City/Radio Shack salesperson but it don’t hurt to try. I would try Radio Shack first. But you still need a list that explains who,what,where and how.
I’m not a fan of Best Buy’s Geek Squad, but I’ve had wonderful help from “Firedog” over at Circuit City. If I go into the store, they’re great at answering my questions and walking me through the product aisles to show me what I need.
But BB is right, go in there with your needs neatly spelled out. We have two computers in the house - mine is hooked up to the Comcast cable and my son’s is hooked up to a wireless router - works like a dream and it doesn’t cost me any extra per month!
