You could pick up a TL-34 body and P60 adapter from Oveready (available in natural HA currently) for $55. Then you could use a number of P60 drop-ins. Just add a Surefire p/c/z compatible bezel and tailcap and you're good to go! It's a good platform with very many possibilities. Alternatively, you could get a TL-65 and run 2x18350s for higher voltage applications.
