MASH (gotta catch up, though, I'm 2 behind including season 8)
Buffy/Angel

I'd love to get the X-Files but I was just so disappointed with the way it wrapped up that it tarnished the series as a whole for me.

The Shield <- Best show currently on TV.
Millennium
The Lone Gunmen
The Simpsons
Curb Your Enthusiasm
Harsh Realm

Mostly Sci-Fi for me (I have no patience for sitcoms and the like):

Firefly would be my favorite by a wide margin.

Babylon 5
Star Trek: Deep Space Nine
Dark Angel: Season 1
Stargate SG-1
Smallville
Buffy
Sherlock Holmes (the Jeremy Brett series)
The Sharpe's Rifles series (but they have very poor video quality on the BFS DVD release and were sold as individual DVDs, not a set)

I enjoy Seinfeld, I really do. But I can watch it two or three times every weekday on TV. With that kind of exposure, I just can't see spending money for the DVDs.

Favorites:

Simpsons
South Park
Homicide
Nip/tuck
Star Trek TOS

I still think Artisan's "Twin Peaks" Season One is best, both for quality of the show and the DVD release.

FIREFLY (one of the best sci-fi shows ever)
Sopranos
The Shield
Buffy
Angel
X-Files
From the Earth to the Moon

"Spaced"
"Degrassi Junior High: S1"
"Freaks and Geeks"
and very much anticipating "Scrubs" to be.

of course those are the only ones i have, but i like 'em.

It has been so long that I actually forgot about the Sopranos!

Out of the dozens of shows I collect and watch, The X-Files are the only sets I give special treatment to. All of my DVDs are shelved except for my complete X-Files collection which is stored behind glass in my audio cabinet for added protection.

There are certainly many other great sets in my collection like Seinfeld, Futurama, The Simpsons, Buffy, and Angel but they aren't treated the same as my personal favorite.
