The only updates requires would be a swivel head and a "standard" 1/8 miniplug sync socket.
In the cagegory of affordable off-camera flash units, the Vivitar 285HV is a worthy contender, along with the Sunpak 383. The Vivitar has a zooming head but no swivel. The Sunpak has swivel but no zoom.
Both units have a specified GN of 120 feet, but I suspect this is measured at full 105mm zoom on the Vivitar, which means the Sunpak most likely packs more punch for shooting into umbrellas or other wide-angle work.
... and if you thought the 8.5 second recycle time on the Sunpak was bad, try 10.4 seconds on the Vivitar! (Both will do better with NiMH batteries.)
Now if someone would only make a cheap, dedicated automatic flash with AF assist!

The "old" version of the 285 also had full, 1/2, 1/4, and 1/16 manual power settings (1/8 was missing). Has the new one plugged up the missing 1/8 power hole.
The place that you set the power levels on the 285 was just below the flash head. I found this more difficult to deal with than the Sunpak flash units (Vivitar harder to get at when inside a small softbox, or attached to an umbrella). The 383 has the manual setting on the back of the flash, this is just easier to deal with.
The sync connector on the Vivitar is also a bit more obtuse, so homebrew cable adaptations that make ad hoc studio use easier, are a bit more difficult. Jacks and adapters that will fit in the 383 are available at Radio Shack (but not the Vivitar).
But, the Vivitar is a nice flash, and there is a ton of after market accessories and light modifiers already out there for the flash (far more than for the Sunpak 383).
Enjoy! Lon
