I have the 285HV and and have been quite pleased. It has a lot of
power and adjustments for the price. I just got a set of Cactus 2Vs
triggers last weekend and found the 285HV to be unreliable when
connected via the hot shoe. I got it to trigger a couple of times
(I'm not sure how.), but most of the time it didn't work. It did
work perfectly every time with the PC cord.
I also have a Vivitar 2500 (12v trigger) and it works perfectly from
the hot shoe.

Tell me what you have found out. My K100D had the same problem only
triggering a pocket wizard (supposed to be universal as your Cactus
2Vs) . It could fire another flash through the hotshoe though.
Some people (mostly Nikon/Canon guys ) mentioned that it was the batt
about to be depleted. Try it and let me know if this applies to all
Pentax flash.
