Yeah that's the strategy I used to use, when it gets old it becomes a donation to my friends. I had a bunch of laptops with 3 year warranties and that usually meant 2 years for the friends, this last laptop is the first one I've had to last more than a year with me, the current one maybe less.
Anywho, my favourite brand is HIS, but I have to admit it's for the added features, because their customer service and replies to questions have become progressively worse. I even know their Canadian dist, and I find they have difficulty getting info. I love their feature, I like the usual build quality, but if customer supoprt is at all on your radar then it's a consideration. For quality and service I have found that ASUS has been the best from my close experiences. I found Sapphire suprisingly mixed with Wicked and Crap service, to me usually things work within the 30-90days I get from the retail location, but when I recommend things to friends I often hear back afterwards, and if the service really sucks they come to me of course.
I have to say though, the two comapnies that impress me the most for customer service are eVGA and BFG, people of course have their issues, but consistently I have found them to have quality products, and good support. And it's really hard to argue against lietime warranty (or double lifetime) and a solid step-up program (even if it's utility is usually a limited window of best fit).
I'm not sure about JJ, people come and go, and unfortunately I mostly notice people as gone when others mention it.
