Any experience with PIAA bulbs?

I'm thinking about getting Xtreme whites for my 1990 535i. I haven't found any true xenon applications for my car, and am wary of paying $500-800 right now anyway.

I would like the illumination pattern and headlight color to be similar to xenon, but abhorr the blue or purple tint as seen on many "tuned" Japanese imports.

Does anyone have PIAA bulbs in their car, and how do they look?
