Check out HTG Supply online, they have a 6" fan and carbon filter for 200$, that would be more than enough, I think around 450 cfm, you could probably even get away with the 4", a little cheaper, especially if you can figure out a way to get the light ballast out of the room. Depends on your stealth requirements, whether you rent or own, ie if drilling holes in walls for cords and such is an option. Good luck, good to see you did some research first. I read for a couple months before I had the nerve to make my first post.
Edit: don't know your financial means, at the other end of the spectrum is a 6" inline ductbooster fan, around 250 cfm, for 27$ at Home Depot, lotta range there, I know.
