Heya,
If budget is a big factor, the 35mm F2 is a great way to go. $300 typically, sometimes less, even new, on Amazon. Very sharp, great lens. For $500, you get the latest version, with the latest coatings on the lens, slightly better glass, IS, etc. I had to weigh in on this myself too as I was in the same boat. Not looking for a zoom, regardless of L quality or anything, as I just don't want a zoom. I wanted prime. But didn't want to buy a $1500+ lens for the kind of work I do. After trying a few 30~35mm lenses, I ended up going with the 35mm F2 IS. After having used it a lot and I do a lot of night and low light shooting, I've come to find the IS very good. It handles glare/flare quite well too, even without a hood. So ultimately, with the performance at F2 and the speed of it's AF and the wonderful contrast/color, I'm very satisfied with the 35mm F2 IS. It's a lens I'm trusting to take photos of my latest newborn, which to me, is way more important than printed "tests" that are being compared by some. I like using real world results.
Very best,
