Yes, if the owner had done enough research, he wouldn't have gone the route he did, most likely.
John, I can understand your point of view and I am sure that it seems that not enough pre-purchase experience was done. But I would like to point out the research that I did do: I talked to New Mexico Skies which owns many PD15s. They recommended them. I talked to other owners of PD15s and they told me what they did to prevent possible problems with them. I drove to Orlando to see the PD15 in production and I talked to Jerry, the owner of Technical Innovations. He explained how to avoid many problems that can occur with the PD15. I examined a PD15 in production and Jerry explained how each system is designed.
I asked other experts as well, including one that installs all commercial domes around the world on a routine basis. He recommended the PD15 as well.
Perhaps what you are referring to as "not enough research" involves the posts about the PD15 on CN. I did read as many posts as I could find on that subject. However the problem with relying solely on that approach is that it is far more likely that a reader will post problems with their PD15 than they are to post successful experiences. So relying solely on CN posts creates a selection process that can be expected to be skewed in one direction as opposed to the other. I did not consider that (alone) to be a scientifically sound approach. I balanced all sources of information together.
Please also keep in mind that I am not saying that a properly built PD15 is or is not a good product. That is not my purpose on this thread.
