Nezff,
When I wrote my eariler post I didn't realize you already had RF 62's........... that being said, I really don't think you'll achieve 200.00 more enjoyment from the 82 VS 62's. Now if you were jumping to the RF 83 I say go for it. Thus my comment below: Good Luck.
I am assuming you bought from an authorized Dealer? Just take them back. Even with a restocking fee, it's better than waitng to see IF you can find a buyer...............Just an Idea.
