Ok from my unders standing the 950 is an update to the 970. I have an insignia with pass thru. is that the same as the Zenith? I have one coupon left and need to use it now. A store in town has 3 zenith left. but I do like the timer idea. have these been compared before? and am I correct that the insignia (2nd gen) and zenith are the same? if not whats the difference. is the digial stream 7700 worth anything in comparison also.
