I bought a few but then I realized that since I already pay for Netflix there is little reason to continue buying them.
Shows like 24 and The Shield, once I've watched them it's going to a very long time until I might want to watch them again so why buy it?
I'm currently watching The Job and The Shield S2 from Netflix.

What I do own is:

Sopranos 1-3
OZ 1&2
Band of Brothers (this one is worth owning)
Millennium S1
Honeymooners complete series (another one that's worth owning)

I'm so obsessed with my favorite TV shows that I watch all my TV sets at least once a year. But, I also limit my TV set purchases to only my very favorite shows.

Back when they announced the first TV on DVD season set, the X-Files season 1 back in 2000, I made a list in my head of all the shows that I thought I might like to own on DVD. I realized that if I bought all the seasons of all of them, I would end up owning thousands of DVDs of TV shows, and I'd probably watch most of them only 1 time. So I widdled away, and made my list smaller and smaller and smaller.

Besides the shows that I listed, there are a few others that I am hoping will get released. And I keep toying with the idea of maybe buying a few others that have already been released. But overall, I am keeping my TV collection pretty small.
