PK had some pink flashlights (protoz?) on his web site. Perhaps you could persuade him to part with one of them??? Now THAT would be a collectible.
Or in the alternative, have you seen the translucent colors for the UKE 2AAA mini pocket? No pink, but there was a red, a blue, a purple, and two other colors (on the UKE web site: uwkinetics.com). If I remember correctly however, although five translucent colors were shown, prices were listed only for two of them... Might not be pink, but the see-through colors make a fashion statement of their own. Some glow paint could make the light even more fun...just a thought.
