I wouldn't say I am a fanatic, but perhaps I am well on my way.
Most of my vinyl is rock and folk from the '60s and '70s, and while I'm not too picky if it's been rereleased recently, I still prefer an excellent/mint copy of the original release than a sealed copy of the new release. It's all for aesthetics to me; I just like the authenticity of holding the real artifact from the times.
I'm no audiophile, but I do agree that vinyl has a warmer quality than CDs which can be too glossed over and sterile a lot of the time. I also the love way you put the needle down and there is that brief pause before the music....life's simple pleasures.

Then there's the wonderful artwork, which I can sit and look at for a long time, unlike CD covers which are usually a few second deal. Hell, I just love vinyl.
My main focus right now is completing my collections with certain artists, I'm almost complete on King Crimson and Neil Young so far. Also the coolest psychedelic covers from the '60s, and it doesn't matter whether the album is popular or obscure. As long as it's colorful and absurd, I'm down with it.
We have a used record store in town where lots of great old albums are only about 5 bucks. Sometimes it's great to go sit in there even when you don't have any money, flipping through the records for an hour or two. So relaxing, lol.
