As many people have said, other than shining light, the two product lines are for different markets.
I am a recent "flashoholic", in that I have always been interested in flashlights, but did not discover that there is life after mag-light until recently.
I was about ready to purchase a high end light (actually Streamlight, instead of Sure Fire), but I purchased a Princeton Tec Surge first, and am very happy.
The Surge meets my needs, I am very impressed with it, it puts out almost a "floodlight" of light (as opposed to a tightly focused beam), and I saved a bunch of money.
As far as "propritary" bulbs in the Princeton Tec products go, I agree in theory, and you are correct if they go out of business or start to charge outragous prices for them, the consumer suffers. However, sometimes, to make a superior product, you have to make a special bulb to meet your application. That would be great if I could go to Radio Shack and get a bulb for my Surge, but I want the brightness and quality that my Surge currently gives me.
I would have to ask the question, if there were other bulbs like the Surge, and they were readily available, wouldn't that mean that there are other products like that also?
I wish that I could go to Wal-mart or my local sporting goods store, and pick up a 20-30 $ light that is as bright and as lightweight as the Surge.

Princeton Tec and Surefire are only competitors in the broadest meaning of the term. Other than we hobbyists, the product is targeted for two different markets.
There is something I dislike about both brands. While both being great products, the replacement bulbs are proprietary. Some PT products, such as the TEC 40 can use an off the shelf halogen replacement, but some, should the company disappear or charge unreasonable prices, do not lend themselves to continued use. Proprietary accessories produce obsolete products.<HR></BLOCKQUOTE>
