Cheap places to get Nikon Nikkor DSLR lens's?

Hi---
So recently I made the step into DSLR photography and I love it! However, I have a question. Now don't get me wrong, I knew in my fullest capacity that a big part of the investment into DLSR photography was going to be the lens's, I mean it's all about the lens's you use these days, but does anybody know a good place to get lens's inexpensively. Now I'm fine with paying the full price, I made the decision to enter the DSLR/ lens world and will stick with it, but just like an online place that does 20% on their products, or something like B&H that has a TRUSTWORTHY used department to help out a little? I'm using a nikon camera…

Samys camera in Los Angeles is a great dealer and they have used gear.

Where do you live? Would have helped knowing that.
In Southern California some of us go to these camera shows.

Otherwise…
Ebay
Craigslist
Swapmeets
Samy's Camera in L. A.
B&H is a good shop
Adorama in NY

If you are looking for used the best place I have found is KEH.com, and the worst is eBay (unless you really know what you're doing). I will buy from eBay but look closely at feedback, many online retailers also have an eBay presence, like the aforementioned KEH, Jack's Camera, etc. And I always feel better buying from them.

Sounds like you may find the 2nd hand market worth investigating. Some amateur photographers (i.e.those doing photography as a hobby rather an income generator) tend to change lenses as often as drivers change direction and the kit is still capable of "producing the goods" A reputable trader will offer a reasonable guarantee (usually 6 months) so this may be worth the investigation - especially if the kit has had minimum use before exchange.
