any small manual flashes with adjustable power and "conventional" form factor?

Hi all,

Anyone know of a good small full manual flash with adjustable power *other than sunpak PF20XD*.  The PF20XD is almost exactly what I want, but the unconventional form factor would make it tricky to use with my flashbender and other portable softbox thingies.   I already have a YN-560, but I want something small.

The form factor for the RD2000 looks great, but it seems like that one is TTL only and no thyristor.  I actually have a Samsung SEF20a which is a rebadged RD2000, and I may just try firing that one off camera at full power.

Thanks.
