bought one of these from Sleep Country ... tons of great info in this thread on what you should pay, etc (basically start at half the asking price and go from there):

Also, Sleep Country does have a great warranty program - 10 years. Just recently my buddy had a mattress from there for 7 years and one of the springs went sideways. They sent an inspector out who verified that it was broken and refunded him the full price he original paid after 7 years... made him a life long customer.
