After being stable for over a year on L278, the SW went so far down hill that I could not stand the crashing, freezing, and non-stop record bugs that were created after L278. After several timers did not fire (because the unit had crashed and needed a power cord reboot I finally gave up on the $1000 921 I bought in Jan 2004 and leased a 622 for $6 a month. With rebates the total up front cost of the upgrade will be $0.00 and Dish installed it 4 days after I called. (I had already bought and installed a Dish 1000 and peaked the signals, so I was able to use my internal wiring. Of course my monthly fee will go up with the lease fee and required HD package, but $6 a month is 8 years to equal buying a 622 for $500.
