A lot of us are in the same boat right now. I got lucky and picked up the last three LSP had in stock. The rumor is that drlava is thinking about another run of flexdrive V5's but only time will tell. For now unless you can find someone willing to part with one of them the microboost may be the alternative for you. Keep your eyes on this thread. http://laserpointerforums.com/f67/flexdrive-v5-gone-forever-54752.html
Hmmmm and to think I have a perfectly good flexdrive and two microboost drives just sitting here without any need for them. Maybe I'll just hold onto them.
