Shameless, Frank... lol
Well, I have attempted to look at this objectively and the more I think about it the combo gun might be the ticket. It seems to be the overwhelming "I'd like to have one but would never buy one" choice.
With that in mind it makes perfect sense. Virtually nobody's got one but we'd all have one if they were the price of a raffle ticket. I wouldn't buy one but I'd sure buy a raffle ticket or two to help you out and if the bonus is I win, well great!
I'm no psychologist but methinks the best raffle draw would be something "different"...
Or, wtf do I know!
