Some say that hds is a rip off from ARC (rip). Some say that things got stolen and we should not support HDS lights. I say it's a damn good light but a bit expensive.

Try also Surefire L1 LumaMax (L1)

And not to forget Peak lights (M c K I N L E Y S E R I E S)... Reasonably priced and relatively new.
