boss,
how much are you looking to spend?
An incan 6p will still set you back between $35-$70 on ebay and elsewhere, depending on how good of a deal you can get, and a stock LED model will be roughly the same.
A few people on CPF sell bored out surefire 6P bodies that take a 18560 battery, and i've also seen them on ebay for a "buy-it-now" price of $10.
You could use the twisty (or even by a surefire clicky aftermarket) and buy a bored body on CPF marketplace/ebay and then add a custom "drop-in"
I know malkoff m60 type drop-ins are made for the surefire 6P and come in many different types and tints and are very good. There is a cpf member named
nailbender here that also sells
many different quality drop-ins as well. Check them both out. ***Make sure you use the correct battery combo no matter what you choose to go with, you don't want to fry your new led with too much voltage!
:mecry:
If you wait and watch a solid 5 or 6 days on cpf marketplace, i'm sure a modified surefire 6p will pop up, probably with an already bored body and a r2 or similiar drop-in for around $40 - $60, I would just recommend this route, as it will be the cheapest and most hassle free.
Hope I helped, the 6P has been around for awhile, and the reason is because they are bulletproof, good choice.
