I get the DAN Preferred plan for several reasons.
1. I want the best coverage in case of a problem that can be extremely expensive.
2. It is really cheap insurance at any level--why not spend a few more bucks to get the best?
3. Although I have never used DAN in terms of needing insurance, I have used them many, many times in the past. I have called and asked questions. I have sent emails and gotten informative responses (Just did that today, in fact.) I have searched their site for information. I have learned scads from their articles. In short, I am very glad they are there, and I am willing to pay my share to keep them there. That is the final reason why I pay for the highest level of insurance, whether I will need it or not, and it is also why I include a contribution when I do.
