I had the same issue with TDD in Rails, where my functional tests were so brittle that they took more work than they saved, and my unit tests were so simple that I wasn't getting anything useful out of it. What I really wanted to know was "will my site work," and I found Cucumber+Webrat to be an efficient way of being sure of that. I TDD Cucumber scenarios now, and it makes me more confident without feeling like I'm spending all my time fighting with a testing framework.
