Lights & Door mirror advice

A general inquiry for replacement head light which are the main beam units as the chrome has deteriorated (inner pair) so the pair need replacing. Can anyone recommend replacement as no doubt there are some cheap replacements on ebay, but I am after quality.
My second inquiry are mirrors as my car has never had any fitted and although I have seen a few P6's with wing mirrors at shows and in magazines, I just do not like the look as it departs from a slimline look to an awkwardness and prefer doors which certainly look nicer and offer more safety as to the traffic around.
I am after anyone's personal experience on the best site to obtain them from. Regarding door mirrors, I am after a solid feel with decent chrome, not a cheap copy, even second hand ones would suit and I would have them re-chromed.
Thanking everyone in advance.
Best regards, Dave
