Shostakovich Jonesing

So I wonder where all the people who love Shostakovich are, if they're not on twitter?

I want this complete set. I love the Brodsky Quartet but theirs isn't available on digital download and I'm too impatient unless there is absolute reason for getting theirs over the Beethoven Quartet's.

I know the Beethoven Quartet is totally reputable and all, but I just want to make the right choice.

Can anyone help?
