Tough call:

WB
ABC
FOX

closely followed by:

Cartoon Network
BBC America
NBC
UPN
HGTV
TLC
Food Network
Style Network
USA
Discovery

All of these stations are non-negotiable. The rest I can take or leave. The only thing I watch on CBS is Joan of Arcadia, and I wouldn't be heartbroken if I couldn't get it. I used to watch a lot of Nick at Nite and TVLand for my classic tv, but they suck lately - and my favorite old shows are coming out on dvd slowly but surely anyway. Used to watch Sex and the City, so HBO was non-negotiable, but now that it's gone I cancelled my subscription. The other great hbo shows are coming out on dvd. Too bad I can't choose to pay for only the stations I actually watch.

SpikeTV (RAW, MXC)
VH1 Classic
Comedy Central (Daily Show, South Park, Chapelle's Show)

Runner-ups:
CBS
NBC
Fox
Fuse

FX (The Shield)
HBO (Sopranos/Carnivale)
NBC (Scrubs)

Comedy Central- The Daily Show
Food Network
Game Show Network- I gots to have me some Richard Dawson.

Very tough...

1. FX (The Shield)
2. Fox (24)
3. CBS (King of Queens)

Comedy Central (Chappelle's Show) would be next.

FOX (24)
CBS (Survivor)
Travel Channel (WPT)
