hey thanks for all replies, I'll spread some rep shortly, good info on here.

the only reason that we got Comcast is the internet. So we added the basic TV package on top of that (goes up to about channel 82 or so), just to have some channels I guess. So we got that box that came out for free, so it is the smallest one. But I'm thinking that we pay too much, as the bill usually comes at about 100 bux/month. I mean I'm only watching like 5 channels max - Speed, SyFy, Discovery, History, and maybe CNN sometimes, and the GF watches like 10 ...

What I got as impression is that same channals that we have from 0 to 100 repeat themselfs from 800 to 900 but with HD quality, so this is where I'm hoping to get some advantage of having new TV.

I'm leaning towards the small one though
