Has anyone try using them as studio lighting with a soft box or umbrella? I read that they automatically shuts off (stand by) after 90 seconds and you have to turn it on manually, which sucks.
If I remember correctly, only the 430EZ and maybe the 420EZ have manual capability. As has been said, you can go completely manual (flash and camera) and use them. I've been told that this can even be on-camera, but I have never had the reason to try it. I use my 430EZ with a cheap wireless trigger system and they can work well.
The auto shut-off is sometimes a bit of a problem. I am not sure it is 90 seconds, but when I am changing something on the set or otherwise wait too long, the 430EZ will turn into stand-by mode. Waking it up is not so difficult since all you have to do is push the test fire button (not turn completely off and then on again).
The 300 and 160 models will only fire full power and that limits their usefulness.
You could sell them, but don't expect a lot for them - it is rather easy to check the auction sites to see what they have been selling for. I was also surprised to see a used 430EZ at a local camera shop for less than I picked mine up on that popular auction site. So the auction site route may get you the best possible return.
But since you have them, give them a try. That will help you figure out what other features you want and which you can live without. Any equipment you buy to use the 420 and 430EZ will also work with any other flash you decide to get later.
