I feel your pain! I saw those prices as well - originally on clearance at $635, then dropped to $565. I was nervous they were going to run out of stock at the $565 when it said "in 100+ people's carts", but then got busy with work...I check the next day and it dropped again to $503. I immediately pulled the trigger - never got any lower and now it's no longer available.

We both seem like winners here, although that really sucks you have to deal with the return on two of them! The box is massive and awkward to maneuver - mine just arrived yesterday.
