I got mine tinted about 3 months ago at a reputable (and SVX experienced!) shop for around $200. 20% on all windows, including a 6 inch strip across the top of the windshield! Very nice on hot days and I love the look! I know it is illegal here in Washington, but I've had it on just about every car I've owned and never a comment from the cops, even when being pulled over for something else. Hope the trend continues with the SVX.
On a side note, when I had my '97 200 SX SE-R, I had 5% all the way around. (no windshield strip, the SVX is my first for that) It looked awesome, pretty much impossible to see through from the outside under any conditions at any distance. But it also affected driver visibility, especially at night. Not the best for a daily driver.
