I decided since I am shooting a wedding Saturday that I needed something real quick. Ordering some cables from a new company Flashzebra I noticed they had a unit for only $66. I figured why not give it a try.
An added advantage is it can be used with 4 cells or 8 cells and it also comes with a nice carry case. I have played with it some and I never have to wait for the flash except on high power (manual) at 150mm zoom. Then its about 1 second for recharge. That is with 1.2v rechargeable batteries with 1.5 volt Alkaline you could probably get away with faster cycles.
