721 users moving to a 921

[WeeJavaDude]

Currently I have a 4x3 HDTV with a 721 hooked up. With the price drop, I was thinking about moving to a 921 to take advantage of the HD I have in the house. Any previous 721 users make this jump and if so any regrets? I am aware of the double buffer issue.

I also would need to get my antenna signal back to the 721. It is currently hooked into my 811.

Antenna ---> PreAmp ---> || ---- Preamp Power--> Anntuetor --> 811
^^^^^^^^^^^^^ Family Room Wall

I would think I would need to do the following

Ant -> PreAmp -> Splitter -> || -- Pre Power-> Anntuetor -> 811
^^^^^^^^^^^ | Family Room Wall
^^^^^^^^^^^ |
^^^^^^^^^^^ --->Diplex --> || --> Diplex --> 921
^^^^^^^^^^^^^^^^^^ Bedroom Wall

Make Sense? Missing anything? Sorry for the crudeness of the document

Might need to move the "pre power" before the splitter

For one thing I hope the 921 is more bug free than the 721. I tend to think that if they can't get the 721 to work right they sure won't be able to fix the 921.

Also, don't forget that they will charge a DVR fee on the 921.

I have the 721 and 921 I would drop the 811 not the 721 or keep all 3
