Yeah, I think I get pretty good results as long as I take my time to set things up properly. I can't remember off the top of my head what ISO/Aperture settings I use, typically, I just switch to manual mode and increase the ISO level until the photos are bright enough. I don't find it too cumbersome to switch either, it's just taken me a little while to get used to it.
Yeah, those lenses are expensive, it's just that the primes let in *way* more light. I bought a 50mm prime and it's great for indoor portraits. Of course, for that I just could have bought a bigger flash. I doubt that I'll ever buy that lens that I linked because I'd have a hard time justifying the cost. Still, it's nice knowing that if I ever did get that serious, my camera's compatible with it.
