Welcome to BLF, Brunswick! Glad you came out of the shadows. :)
Your best bet for a quality AAA light at a good price would have to be the CQG S1 stainless steel.
It's the thinnest AAA light you can get anywhere and is extremely well machined from stainless steel. Here is the thread where it's currently available for $15 shipped. Old4570 has done a review here.
If you want just a cheapie for under $10 look no further than the Black Cat. You can find them at DX and elsewhere and are highly regarded by many of the members here.
Good luck!
Johnny
