I have ordered from http://www.classicarms.us/ and while it took a couple weeks to process my order, and bill me for that matter, I found the staff helpful and what I ordered arrived well packed as described at my local ffl dealer. The web site was slightly out of date though as one item I wanted was out of stock even though the web site listed it in stock. As such while I recommend them I advise a phone order rather than via the web.
I have also used http://www.cheaperthandirt.com/ for ammo and accessories with no complaint and suggest everybody sign up for the free catalog... it's good bathroom reading and if you highlight what you want your spouse has an easy x-mas list. I got a grappling hook for my birthday

http://www.midwayusa.com/ is good for ammo
my father has ordered from http://rguns.com/ with good results
So what other sites would you guys recommend for a fairly new noob?
