Kilo, feel free to contact their rush chairs. They probably have their contact info posted on their website somewhere. If you're joining for the national organization (which I gues you are since you want to join only Delta Sig) why does it matter what the chapter is like?

I'll tell you that I'm damned glad I'm a Sigma Nu, but there are chapters that I sure as hell wouldn't have joined.

I'm with many of the people above here. Choose the school and then worry about the fraternity you want into. If Delta Sig is up to your standards there (and you're up to theirs), bonus! If not, c'est la vie. Choose another.
