where to buy a weapon light host

I want to build a weapon light for my 12 gauge but can't justify spending over 90$...so I am going to do a build..my first build to post on the internet..I have 6 flashlight builds under my belt with some lathe work and 1 high power laser...so.I'm not totally new to the game...I like that weapon lights have a rocker style switch on back..I'm looking for a host that is 1 cr123 compatible....where should I go for a host...is tried searching google for well over an hour..I want something of decent quality.....I don't mind spending a fair amount on a host seeing as how I already have the led and batteries and pwm circuit.

Bump nobody?

I've bought weapon lights and parts of weapon lights on the big auction site. Keep looking and soon you'll find what you need.
