Well guys, guess what I found. My old Vivitar Auto Thyristor 225! And even better, it still works. Now my question is, can I use it with my Nikon D5000? I know it works, but will it do anything "adverse" to the camera. I've read a couple of things about voltage feedback, or some such, and want to make sure before I go to town with it.
And just in case anyone is interested, I managed to find a manual for it. And many others. Check out this link.

You need to be careful - very careful. Flashes of that apparent vintage usually used very high trigger voltages (> 150v, usually over 250v). Your camera wants a 12v trigger, and mixing the two is a big risk. If you are bound and determined to use it, a Wein SafeSync or similar is advised.

Welcome to Nikonians! Here is a link that has flash triggering voltage listed: http://www.botzilla.com/photo/strobeVolts.html Unfortunatly the Vivitar 225 is not listed, though the other models with a similar vintage exceed the safe triggering voltage by a wide margin. You should verify the triggering voltage with a volt meter and or use a Wein SafeSync: http://www.adorama.com/WNSSHSHS.html?kbid=912610&searchinfo=Wein+SafeSync to be safe. Call it cheap insurance. Of course you will be limited to using the camera set in Manual exposure mode with the Flash in (non-TTL) Auto flash mode or Manual flash mode. Good Luck and Enjoy your Nikons!

Well, I would DEFINITELY advice you use something like a Wein Safe Sync to isolate the camera from the flash.
Having said that, a dedicated I-TTL flash like an SB-400 or better SB-600 or SB-900 would be best as it maintains full compatibility and can properly expose a shot especially when full power is not required.
