I would have to say "A". I will make the decision quickly has to who to buy from and what I want, so "B" is not that big of a deal. As to "C", I just purchased a home theater system and spent two days with the instruction book trying to get the thing to work. After a couple of rather nasty outbursts about the manufacturer and the insane technical writer, my wife called the store where we purchased the unit and a teenager showed up and had the system working perfectly within 1/2 hour. Therefore (unless Barb makes house calls) I probably won't try to make my own.
