johnny_wobble, you're right... it's good to avoid old Vivitar 283's and such if you're ever going to accidently put the flash in your hot shoe.... without remembering not to.....
If you use radio triggers, no flash will fry your camera, but some flashes may fry some radio triggers.... i.e. old vivitar 283 on yongnuo RF-602... whereas a Cactus V5 trigger will take up to a 250 volt flash, and it uses AAA batteries, costs about $25 each too...
http://www.lightingrumours.com/c…some cameras take up to 250 volts, some only 6 volts... entry level canon's are often 6 volts...
a list of voltage tested flashes:
http://www.botzilla.com/photo/st…you can test yourself if you have a volt-ohm meter and do a bit of googling....
Most Sunpak 433/383 and all (I think) yongnuo flashes have trigger voltage under 6 volts...
Some studio flash (especially old speedotron blackline) have over 100 volts trigger voltage, but can easily be radio triggered..... or light-sensor triggered (button on the powerpack)
