As per Heinz' post on the subject, HpH is interested in finding out how many people would buy a Kingfisher catapult if they made one. So, to assist in their market research, I've started a poll on the topic. They don't need to know if you're interested, only that you would buy one. In other words, they need a firm sense of potential sales numbers before taking the risk. If you're in the "it depends" category, just choose "Maybe" - but for HpH, only the "yes" votes will matter.
Have at it!
