The floodgates to my wallet have opened

and I am starting to build the Walt Disney Treasures DVD collections and other DVDs I've missed.
I've got the Tomorrowland DVD coming and on ebay I'm watching a Disneyland USA, which I intend to place a bid on.
My questions are, since I've been exposed primarily to Warner Brothers and have seen only a few Disney shorts collections, what should I aim for first? I'm drawn to the Silly Symphonies and the B/W Mickeys (which I've never seen more than a couple). I alos realize I'm going to be paying a premium for some of these since most are now out of print.
Is there a listing online of them and other Disney DVD releases? I've not googled myself yet, I'm going to be an a$$ and assume someone on LoT has a link or a list.
The other thing I am looking for and will likely pay the piper for is the Fantasia Anthology set.
I'm not so much interested in some of the live action, say Mickey Mouse Club, Spin & Marty and Davey Crockett DVDs. Call me a heritic if you will

.
Now that I've been back to Disneyland....lookout and I guess I had better start putting in some OT to pay for all of this.
