Yepp, I have a 250 too. Lovely camera. I cleaned it up and did the AAA conversion. Used the battery holder from a cheap 4.5v LED torch. Mine works a treat. The only aspect I have had to work around is the electric eye is less sensitive than it once was. A one stop compensation on the darken/lighten wheel is all that is needed. It's enormous fun at parties and events, giving away prints on the spot make for many a happy bunny.
