Help sourcing high quality parts

[cambel]

I have a few lights that I want to mod/upgrade. I know dx sells a bunch of different stuff but I would like to find the highest quality parts I can. Specifically I am trying to find a high quality quiet forward clicky switch with momentary, amongst other parts. Where would you guys recommend. Just to be clear I am looking for the just the switch so I can solder it on myself.

This one has a lot of diving-specific stuff in it, but there's also a lot of general info available in this thread.

Wow thank you. I spent a few hours last night looking and didnt even make a dent. I wish I knew what switch was in my pentagon light cause I love it. Its got epoxy on the threads though and I dont really want to break the seal. Gonna go look some more.
