>If someone offered me it for $25 - I would pass it, since I have no place to put it nor I have time to watch it.

Growing up, I hunted down free and really cheap computer hardware. I've always had a sizable stash of equipment that I'd play with, learn about, and eventually use to run services. As I've grown older, the initial purchase price has become less important, and the storage cost has become more important; my current workshop/office is maybe 200-300sqft, and it's got two people and a lot of hardware in it.

The thing is, here the cost is time, not storage space; and I think people learn the 'time is valuable' lesson sooner. But yeah, you would be keeping out 12 year old me, which is fine. Personally, I would think that the majority of people at these events would be past that point. dono.

You'd certainly need to apply another level of filtering; obviously you don't want to listen to a pitch from every joker with fifty bucks, the question then would be how much easier would that filtering process be if you first filter out all the 12 year old lsc types for whom the fifty bucks is a big opportunity cost. Personally, I don't think it would save you much time, but I could be wrong.
