Nitecore P12 is really good, comes with decent accessories( holster, lanyard, tactical grip ring)have you used 18650 rechargable Lithium ions? I think it's better in the long run, get a pair of 18650's and a charger will last you for years, but if you want to save some money can try convoy S2+
I would recommend anything that Malkoff sells, especially the MD2 and the Hound Dog.
