I went with Jag Window Tinting in Noblesvile. He did a decent job. $195 for my 325i with 20% all around including a windshield eyebrow. ($175 without eyebrow.) I wouldn't claim it's perfect but it was a good price and it's good enough for me, I'm pretty picky but I don't get all worked up about something like window tint that is easily replaceable...(as opposed to paint or body work which is much more costly and "permanent").....
Here are a few pics:
