This probably won't fit your needs economically, but it might give you some ideas:

Otherwise, you might want to scout around your house / apartment and see if there is an area you could cleverly block off, and make it blend into the surrounding wall. Won't work with drywall / plaster, but does work with various paneling - T-111, etc. Then, anchor a standard gun safe in the area, block it off and voila - no safe. A friend did that, and he can access the safe in about 45 seconds, but you'd never know it's there.
