H.I.D vs PIAA Upgrade?

Hi all!
Have searched but cant seem to find anything...Has anyone had any experience with either the aftermarket H.I.D kits you can buy or the PIAA H.I.D effect bulbs?
Im looking to upgrade my 1997 P38,(not complete lamp assembly) Just one of the two above kits...
Have read the PIAA Bulbs £70 dont last too long and there are around 6 different "colour tones" But im also a bit wary of the H.I.D kits £80 + (cheap one!) as never spoke to anyone whos fitted one?
All im really after is the later Range Rover/BMW etc headlight effect..The crisp one that catches your rear view mirror....Also i do alot of driving down country lanes in the dark (ooeerr!) To get to and from work 5am and 11pm, so the extra light would be a great advantage!
Many Thanks all!

Hi all.
Always smile when people want to upgrade/improve lighting from rr headlamps as i can honestly say out of all the landy models i've owned they are brilliant. I also love the inboard/outboard description, just class.
