If you don't need a DVR, then I believe you would be eligible for the 211 $49 lease, which would include a dish upgrade, that's worth a fair amount of money. It's an HD receiver but there are no disadvantages for having an HD box.
Likewise you should be eligible for a $299 622 lease too.
And that you would have a good chance at getting a deal on a 625 DVR, but probably a lease deal.
Non lease, they might not offer a whole lot. Dish is into leasing. Haven't heard much of late about $99 purchase offers on older gear, like they used to offer.
