I guess I have raised "being cheap" to a new level for you. See, there's one in every crowd. And today I'm it.

And best of all I don't buy the good ones from the hobbyshop. I buy the cheap ones from the office supply. I think they are about two bucks a bag. I can't remember. I have had them a few years now. But you are right, I have seen a lot of folks pull them off and throw them away after one use. I always get them out of the trash. I hate it when they cut them off. You have to tie the ends together and then they are really too small.
I hope you realize I am kidding.
For the most part.
