Welcome Ricardo! Congradulations on your first post- CPF is a fun place, just watch your wallet. I'm pretty new here too, although I have lurked (read the forums without being registered) and collected lights for a while. I would say most people get lights from 3 types of sources: 1) Dealers over the internet- you can find a list of them and those that have CPF discounts in the dealer forum. Most dealers distribute lights made by other companies but there are several that make "custom" high end lights that as of now are superior to any production models (and more $$) 2)Buy/Sell/Trade forum where CPF members sell their lights to others, or post that they want to buy a particular light. Be sure to read the announcements at the top for the rules of the forum. Ebay is another online auction where lights can be found, but the bidding war can overvalue the products at times 3)Actual Stores- while this way of buying offers instant gratification, not many people can find stores with a great variety of lights or at the low prices that can be found on the internet. Sometimes a CPF'er will post about a store that is having a clearance on a particular model, and if you have the store in the area, you can often find a good deal.
Hope this has been a help,
Jon
