Originally posted by SALUKIS97 I second the lumopro 120 from mpex. It was designed specifically for what you have in mind.
There is also the vivitar 285HV which is super cheap. If you buy a used one, make sure it's not one of the old ones which have too much trigger voltage and can fry your hotshoe if you put it on your camera.
I've been able to snag a nikon SB28, and SB26 from craigslist for under $100. They are my personal favorites at the moment, but you can only find them used.
Good luck, and you wont be sorry no matter which direction you choose.
Great sigfile. Apparently, it hasn't happened yet.
So it goes.
Anyway, to the OP, if you want shoe mount flash units, there are lots of options out there, but keep in mind while people push them at you for "studio" use, studio photographers overwhelmingly choose lights that are designed from the ground up to be used in a studio environment.
I suspect they are on to something, since a lot of them start out with shoe mount strobes cobbled onto stands of some sort and when they can, graduate to real studio lights.
The route I took was a couple of Vivitar 285s on Popsicle stick light stands, and from there I went to a Metz 60CT series flash with a Mecatwin, and finally, 25 years ago, I grew a brain and bought a set of real studio lights, which I still use.
I have no desire to go back to my roots in this instance. I like the versatility of studio lights, I like the power output and fast recycling times, I like the quality of light that they put out and I like that I don't have to tape a MagLite to my flash head to get some semblance of modeling light.
While you may not be sorry, no matter which direction you choose, if you can afford the minimal extra outlay, there is far less chance of you being sorry if you pick up a set of real studio lights.
But don't trust me or anyone else here, go and talk to a few studio photographers. Look at what they are using for lighting. I'm betting that you will see very few shoe mount flash units on Popsicle sticks with MagLites taped to them in any studio you might visit.
Lights like the Flashpoints from Adorama are not overly expensive and will do a far better job in a studio than a shoe mount flash.
