Guys,
Check out
www.safetysystemscorp.com. Our team has ordered from them in the past and have been pleased. They do not stock every item all of the time, so there may be a backorder, but it is usually a reasonable amount of time. I just spoke with a sales rep there within the last week or two and they had the Surefire X200's on sale for 185.00. Yeah, that's no typo...185.00.
You can request a quote online via their website, if interested...especially if it will be a large group order.
