Another option that you can get great deals on but it's sort of a waiting game.

Big box stores like Futureshop generally carry two years worth of inventory. So as new stuff comes out, the old stuff gets cleared out at a reasonable price.

I picked up the SC1227k last year for around $499. The next year model was selling for $1400.
