Lawrence, you can use almost any flash with your D5100. It is just a matter of the shoe voltage, not really an issue with any newer flash nowadays, and the fact that if it doesn't do TTL then you have to expose manually.
I currently use an older Sunpak PZ40X with my D90, no TTL, and I just set the flash output manually as it is adjustable output on the flash itself.
Also Lawrence, if you can get those better Nikons TTL flash units, they can be commanded from within your camera itself withought using those radio transceiver units. That is, if the D5100 has the Commander mode and I am pretty sure it does. My D90 has it and I am sure the newer models, 5100's/5200's, would have it as well. I personally like the radio poppers better and one day will have the units that will use the TTL function.
I will check that.
But …
I cannot believe it!
I just tried my old Sunpak GX14 on my hot shoe and it works. Holy moly I got some more gear without even knowing!! (thanks to you)![]()
Do a quick search on that flash and see what the shoe trigger voltage is on that unit. If its real high, like the old Vivitar 283's, it can damage/ruin your camera.
That is why I bought the Yongnuo radio triggers so I can use all of those old 283's off camera, which is where I want them anyway.
Looks like it may be 160V
That's what I have found so far but still reading
Yes be nice to have it off camera. Might PM you on the set up you use. In the meanwhile it takes 2 AA batteries - does that mean anything to me?
@Vixen Check this out.I recently bought a pair of Yongnou 560III flashes and a couple of triggers. I think they are great. I use them off camera, on the supplied stands, and find them very easy to use (although I did have a bit of a deflating moment when I discovered I could not use them at more than 1/250 or 1/320 as that is the max flash sync the camera will allow).
What I DO find difficult is where to place them in regards to the subject. It's a huge learning curve.
Oh...and make sure you get the upgraded triggers. I bought the wrong ones so can only use them "on camera". That'll teach me to pay more attention when ordering stuff. The 2x flashes and 2xtriggers cost me about AU$210, which is pretty good.

@Vixen Check this out.
This page has an interactive lighting placement thing. You can click on different positions of lighting (1:00 o'clock, 3:00 o'clock etc) and it gives you the result real time. There are several of these on that page using different types of lighting as well.
