As a few people of stated, regulated options are pretty limited (for now but that will change). There is the boxer that is being produced but you will probably be waiting a bit for it. There is another dual regulated coming out the Rage Squonker by Ohm Boy OC. You can google it to find places that are doing the pre-orders. It has a 155W ‘rage’ chip in it and the beta testers were pretty good. Unregulated I haven’t delved much into because I like consistency without having to change batteries every 20 minutes of use or so (just my personal mileage).
