Since you have Tsurus, you have an ECE (European standard) beam pattern. These have a much better cutoff than standard halogen housings (US Standard). I did a lot of lighting research before I installed HIDs in mine. The cutoff with Tsurus is very good, and glare is minimal. I did have to test a few settings with the lights on my garage door and having my friend drive against me with my car, but the end result has yielded a solid beam pattern and minimal glare.
Putting HIDs in factory halogen housings that do not have at least an ECE beam pattern is stupid. I see SUVs and ricers with real HID conversions in US DOT housings and it sucks really bad. Classic owners that want HIDs are lucky that we have access to Tsurus.
The other alternative that I nearly did was retrofit the housings. Using an Audi bi-xenon setup (which can be found on eBay and other classifieds quite readily) you can have proper lenses with some real focus. This requires a lot more work on your part, or paying $200-300 to have someone do it for you. If you really care about doing it right, this is the way to go. I might still eventually do this. By far the best lighting resource for HIDs is this page:
http://faq.auto.light.tripod.com I learned a lot on that site.
Finally, to address the first post- I bought my HID kit from eBay. Yes, they are technically illegal to have now. They were shipped from Canada and are a full H4 hi-beam/low-beam conversion. They are 6500k, which is too blue for my taste- but I will eventually upgrade them to 5300k or less to bring out a crisper white color.
One of these days I'll do a writeup on my conversion experience. If you have Tsurus, you can definitely get away with a straight-up conversion as long as you take some time to aim them properly.
