RANT WARNING....
You know whether it is free, $15, $30 or $150 and all slicked up and in good working condition with new wiring doesn't really matter - some of you would pay a whole bunch more money for a brand new machine that won't hold up near as well as one of these. Just the fact that they are still around and in working order should tell you a lot. These are environmentally friendly - not going to a land fill in a couple years. I bet if you adjust for inflation people were spending a whole lot more money for them when they were new. I've not seen real many free or $15 machines in pristine condition. I've seen some real nice worked over machines for $150 or less - what a bargain - a worked over machine for $150. You can't buy a $15 machine and take it anywhere and have it worked over. End of Rant
