Actually, you might be able to get a better deal with BB's own card. Hear me out.. hehe. Normally, they'll bend you over with their ungodly interest rates, but occasionally (as I think they're doing now), you can get two or three years zero interest on big purchases like HDTVs. Even at "only" two years, that's less than a hundred bucks a month to have the whole thing paid off. Even I can afford that, and I'm a poor boy.
Still waiting, though... even as cheap as the 47" is, there's Black Friday coming up. Might be worth waiting for to see what they do for the holidays.
