Re: Holy @#$%... $120 488nm diode!!
These guys sell Saft 14250s at very good prices $3.79 per. Everyone else wants 2X to 4X that price it seems.

If you're lucky, it's possible to come across some 3.7v 14250s (1/2 AA) on eBay. While a bit pricey, they're the perfect battery profile for pens if you can't find yourself a boost driver. Not sure how much of a beating they can take though, probably under ~3W if I were to guess.
