HD - HV, whatever! You knew which model I'm talking about.
The OLD 285HV has a trigger voltage ~ 6 - 8 VDC (< 12VDC measured on an
oscilloscope). The old Vivitar 285 (*NOT* HV) had unsafe trigger voltage.
I have 3 of them - all 3 tested for safe trigger voltage - since 2005 &
I have used them with the *ist-D, K10D and K20D with no damage to the
flash circuit in the camera.
I bought mine used, so I know they're the OLD ones. I got them cheap
because all the Canonistas were dumping them at the time.
If you're a Canon shooter, you might have to worry, but Pentax *appears*
to have the same tolerance to high voltages that Nikon claims.

In any case, it should be safe to use any hot shoe flash with a trigger
voltage 12VDC or less, and that includes the *OLD* Vivitar 285HV.

No such thing as a Vivitar 285HD. Old 285HV models will fry your
digital camera into its component bytes.

Older Vivitar 285HD, but only if you can find one of the older ones
and not the current Chinese CRAP that's being sold under that
designation.

I need an inexpensive hot shoe flash to use with the K110D & the
K7. What would you advise?

PS: A lot of good, inexpensive NOT CRAP electronic items are made
in China today. Unfortunately the current version of the Vivitar
285HD is not one of them.
