Good tabs are hard to come by. And transcribing is not as easy as some might think (depends on the song). There is a site I visit for some of my acoustic references called Tabpigs that hosts tabs for a couple guitar guys I like. I like their philosophy; they post the PDF version of a tab that isn't available commercially. If one is, they provide the link to where you can go purchase it. There are a great many songs out there that are not available commercially transcribed and I see nothing wrong with the general population providing them.
It's sad really. But, since this is the internet age, just look around a bit and I'm sure you'll find a new site that has all the files. You can shut one down, but you can't shut them all down.
