Ask Engadget: Best holiday gadget bargains?

Even though it's Thanksgiving today it is still a Thursday, which means it's time for another edition of Ask Engadget. Last week reader Martha B. wanted some advice on picking a good digital SLR camera, this week we have a more general question. Tomorrow is Black Friday, aka The Busiest Shopping Day of the Year, so we've been wondering, if you've got any leads on any hot gadget bargains you'd like to share. $5 SD memory cards? $25 DVD players? $1000 plasma displays? Do tell.
