I was in a store this weekend and the only other large screen I saw was an LG 60pn6500 plasma TV for $998 (reg. price) - not a smart TV according to the web site:
A place like Superstore has limited selection, especially at the higher end.
I agree that they probably don't offer delivery.
EDIT: If you're willing to wait, you might see something like the LN5750 in a larger size, but it will probably take a while.
