If light-sabery design is your primary goal then the Haiku is hard to beat. And its a great light too. But if you're a fan of big lumens (and it seems you may be since you want a triple), they're not very bright lights. Very functional, useful beams - but not the sort of beam that's going to impress your friends. Still, it deserves consideration.
But since everyone else has already covered that and you said "chunky ti or copper", that immediately makes me think of Sinner. His lights are definitely not slim little things. He's the only (afaik) semi-custom maker working right now who isn't using a McClicky and his choice of Omten reverse clicky in the tail requires some more depth back there, giving his lights a very distinctive shape. Plus they're triples "out of the box" and much easier to mod yourself than something like the McGizmo.
Here's my copper Sinner, if you want to see what I'm talking about:
Fresh from the package:
After a bit of carry:
And my lighted orange boot, just because...
Unfortunately they're perpetually sold out, like many of the semi-customs. You'll have to hunt and beg for one, or wait and dream until the next drop like I did.
That's just one idea. Okluma's are awesome as well. So are Sigmas. And any of these can be had for around your budget, if you can find one for sale.
