I was fortunate enough to come across two flashes in my attic the other day, both of which my dad had purchased when he had a photography class. Both are working great, and after a $6 mod to one of them, they now both have full manual control of power output.
First off is the Sunpak 333. This bad boy came with full manual control, AND a tilt and pivot bulb. I checked ebay, there is one starting at .99 cents, and several for very cheap.
The second flash I found was a Vivitar 283, the 285 (and the notorious 285HV's) little brother. After some research(SEE NOTE BELOW) I found out that I had the safe version of the flash, and not a crazy 300v trigger one that would fry my camera. However, this little boy only had an automatic light sensor on the front and no manual output. But I stumbled upon an article on strobist (http://strobist.blogspot.com/2007/02/hack-e-flash-heaven.html) on how to make one from a 100k linear pot ($3 at radioshack, and a radioshack project box). After a little elbow grease this baby now works perfectly! So happy I got all of this stuff to work.
What deals have you guys found?
NOTE:Many old flashes have the potential to fry your camera because of their 300v trigger charge, instead of a lower 6-9v one. Be sure to check: http://www.botzilla.com/photo/strobeVolts.html (Which is the holy grail for strobe and flash listings and safe/not safe, check it out). With the 283's, the ones that are made in japan are not safe, the rest are safe.
