I do a few, and can say, first get comfortable with put spreads. Most of the premium is in the put side. The option house pl calculator is handy seeing what you have and will do a condor, and the probability calculator is good for seeing risk. The extremely low risk spreads on indices have been figured out by the market makers and often they have the bid ask spreads larger than the difference between the the strikes so the market says what should be a net to you become a net to them. I have found that often a condor will never be taken and I have to do the put and call separate or give up on the call. I think the biggest issue with these is that to get the risk low enuf, you drive the return down and hence the margin way up to get an acceptable total return.
