One thing that left a sour taste in my mouth:
When I decided to become a Dish customer in May of 2000, I shopped for the receiver I wanted and decided upon the 5000 hands down since it provided future upgradeability to DD and HD. A few months after I bought it I discover it is discontinued and the modules are no longer available from Dish and very hard to find. I also notice that software updates for the 5000 will be few and far between.
That really ticked me off because they advertised it as being so upgradable. Then when the 8PSK comes out, they shut the 5000 completely out of the HD business. yeah they had a 6000 deal for 5000 owners but only if you had the HD module. Well I never was able to GET one, so I didnt have one to trade in, but I still bought the 5000 originally because I thought I would have HD someday.
It goes to show that you cant count on upgradability from most vendors, its usually cheaper to get the newer unit.
On a side note, I once bought a 14.4K modem from US Robotics (Courier model) on a $199 BBS Sysop deal around 1991. I upgraded it to 16.8k, 28.8k, 33.6k, and finally 56k all through FREE software updates and ONE $99 daughter board upgrade. Used the same modem for 12 years (still have it).
Now THAT's upgradability! Then 3COM bought them out and a good equipment vendor passes on.
