Thanks for your response. I'd been putting off picking up a couple of the old nikon flash units at KEH and just saw one of two I was planning on buying disappear. I just now ordered two from Midwest. I figured I didn't have much to lose with their 15 day trial period. Assuming everything works out it will be a better deal than KEH. I'll give an update after I receive them.
One thing to note as I was browsing their site; they don't have a very large selection for used gear.
MidWest Photo is super!! Last week I bought a used Arca reflex hood for my 4x5 and the description over the phone concerning its condition was more pickier than I am and I am picky. It arrived in outstanding condition. Over the past three years I have bought used Hasselblad and Ebony camera pieces and Jobo darkroom parts with absolutely not a single problem. Jim (owner) is a great business man. Buy from him!!
Well, I ended up having to cancel my order. I ordered two speedlights and one had been sold the day before. I really needed two and another one turned up at KEH. I will have to say I was very happy with their customer service. I received an email explaining the situation and asking me if I wanted the order with just the one flash. First rate service. I will take a look at their site in the future for any purchases.
My flashes arrived from KEH. One seems to work fine; I'll test it out tonight. The other won't fire any thing less than full blast! They were easy to deal with; I'm sending it back for an even exchange.
