This thread has been an extremely interesting read.
What I think this all boils down to is supply vs. demand. Sure, there are all types of Zoas everywhere. But, can you get this variety anywhere else? Is it a common strain? Is it a desirable coloration?
All these things will affect a person's desire to own them. If you don't like this coloration or something else about it, don't buy it. If you want nice polyps, I think you have to pay for them unless you are just extremely lucky and somebody gives them to you. Where I am, I can buy brown boring zoas all day long for $5-$10 per frag all day long, but it is hard to find any neat looking polyps that I would actually want to display. I have therefore, been willing to pay more for nicer specimens in other shops several hours away.
I don't think you should diss the seller just because he has put a high price on his zoas. If somebody was selling some other desirable commodity, and they were charging a premium price for it, that doesn't mean that the person is a schiester, just that they believe the value of it is higher than you do.
If $200 is too high, how about $100? If that is too high, how about $25? $5? Where is the line drawn that something is too high or "fair". Why not make people just give everybody else free frags? If you remove the reward of fragging nice colonies, you remove the desire for anybody to frag their zoas. If I can get the same $$ for all of my frags, I'm only going to frag the one that grows the fastest in my tank--brown zoas it is!
