Any 4 x AA torches/hosts around for modding?

Hi all,

Is anyone aware of any budget 4 x AA torches, or hosts that can be useful for modding?

The LD40/PA40 is the first one that comes to mind, but not exactly budget.

There are a couple of 100+LED style lights that take 4xAA, but there is little room for a heatsink/driver in most of them.

Any ideas?

Budget P60 solution, but with 1X4AA it is quiet long. Link to the extensions on the new Kaidomain here (1,2).
