My next purchase will probably be a pint of Guinness this evening.
Oh, wait! You meant what would my next light purchase be? I really don't know. I missed out on an old smooth button Surefire 6P without any writing on the tail cap last night. :-(
I was just noticing how good the condition is of my Surefire 6R is, despite the use/abuse it's seen in the past year. I'd like to put it away and keep it that condition, especially since I have the original box, accessories, and lamp assembly. But, I need use of the MC-E drop-in that it currently hosts, so I'm looking into another (cheaper) host for that. That'll probably be my next purchase.
