Just a quick heads up, Cloud Defensive is doing a trade in right now. They'll take any light, working or otherwise, and give $100 towards an OWL or complete REIN/Micro kit/with mount. The light you trade can be a 'real' WML or a cobbled POS, they will accept anything. This would bring an OWL down to $299, not cheap but IMO well worth the cost (I paid retail!).
