DVR debate

soooo i'm trying to decide if i should get a dvr and which one to get! i think i would like one, but i dunno, i think that i'll end up becoming like sharon and having soooo much backed up tv! heh. but i'm already starting to get a lot of backed up tv on my vcr already, so maybe it's a lost cause hehe. i want to be able to watch my recorded tv downstairs on the nicer tv instead of in the bedroom with the bad tv, and tv upstairs will only work with the vcr connected to it, so moving the vcr downstairs is not an option.

ok so here are the options:
Tivo box:
Pros:
very easy to use
fixed cost ($350)

Cons:
can only record one show
can not record HD

Cable DVR:
Pros:
able to record HD programming
able to record 2 shows

Cons:
user interface really sucks, hard to record stuff
monthly cost ($10/month) might even be $20/month to add digital cable

the new wave of the future is HD, so if i got Tivo, it would kind of be obselete, but i don't really need to record HD in my opinion. the value of tivo is still pretty high, on ebay Tivo boxes with lifetime subscriptions are selling for $300+ but who knows if it'll still be that high when HD gets big. but some people *still* don't have cable, and i don't think HD is *that* big yet so might not be an issue. Supposedly Comcast is teaming up with Tivo and the cable DVR should have Tivo software mid 2006. So next is the cost, *if* the Tivo box doesn't fail within 3 years, it's a better "value" to get the Tivo because it's just a one time cost, and not a monthly cost. I've heard some bad things about Tivo boxes not being able to last over 2 years though, so I'm kind of scared about that. anyone have any problems ??

i *think* i'm leaning towards the tivo and I'll just have to live with only being able to record 1 show on Tivo and then maybe using the VCR if necessary, any opinions anyone?? is the 40 hour one big enough ??
