We bought a 50" plasma as part of a BF deal 5 years ago. It was the highest rated brand (Panasonic) at the time, so it was not a cheapy model. It has held up wonderfully, and we hope to get many more years of service out of it. Two years ago we bought the kids 32" TVs for their bedrooms -- again a great BF deal from
Amazon (also Panasonic) that we've had no problems with. Last year we got a 32" TV for our bedroom to replace the last dinosaur TV we had. It was a cheapy Westinghouse model, but we've had no problems with it at all. Just got 40" TV this year for my mom. My brother and sister are chipping in. For $298 for a 40" TV to replace the crappy tube tv she has is totally worth it.
Got DD a laptop BF deal this year. A decent one, but yes the technology is about a year old. Who cares? She's 14 and will use it for facebook,
youtube, and for homework assignments. Computer technology changes so fast that we don't keep our computers longer than 4 years anyway. This should last her just fine for the next 3.5 years until she goes to college.
I also buy the cheap DVD players each year for $20ish. DVD players are a dime a dozen and wear out, so it's nice to have a couple extra around the house.
Now, the real cheapo stuff like the $100 netbooks, I stay away from. But I'll go for deals on xbox games, Wii, etc... if I can save $10 or $20. I don't buy games just because they are cheap though because I learned my lesson that the cheap games never get played. We also bought our first X-box before BF. No deal there because it's the 250gb model with Kinect. There were no deals on this and they are becoming very hard to find, so we got one while we still could.
Now that we are set for TVs for a while, next year it will probably be a Nook/Kindle or some other gadget that we'll be after.
