My feelings, as well. I have a Pentax 35-80 that gets absolutely roasted in the reviews, and I couldn't give it away on eBay, but if I set proper expectations, give the lens some proper light -- I get some great results. And it has really fast autofocus, too. I'm going to post a photo that I took with that lens, that I really like. I'm also proud of it, as it won a local photo contest a couple months back, and is currently on display in a small gallery through December.
Just goes to show that you can get nice results with most any lens, so long as you set the proper expectation
