Quick request, recommend me a budget 2x18650 light.

Hi, i'm looking at getting a 2 x 18650 light for my friend, I like the 2 cells as the emitter can be driven at 3amps without stressing the batteries. it must have decent throw and be really budget! the skyray stl-v2 looks awesome but its out of price range, brinyte xml900 for $33 seems ok but reports of poor heatsinking abound. Beamtech t6 $37 looks a good deal, is there anything better? Just read about the keygos ke 5, one cell tho but look impressive, how might it compare to the above lights? I should ad that some diy work on them is no problem for me, driver swaps or machining i dont mind as long as its a good deal.
