Ripster, you freaking kill me. If it's any consolation, I had this in my watch list a few hours after it was listed.
Kishy, it is easy to earn enough extra cash to buy a keyboard in less time than you spend on this forum. Seriously, just get a temp job, donate plasma or drill for maple syrup or something.
There are plenty of people on this forum that would give you an excellent deal on a board, including me. And for the record, I remember very well what it was like to be 20 and struggling financially. Go dig through local thrift stores for crap and sell it on ebay then buy as many keyboards as you like. It looks like your sig has plenty of boards you could sell to get a Mini.

As for getting a great deal, nothing at all in the world wrong with that, scoring a great deal is half the fun of getting something rare. Paying a scrapper a buck for a M13 is not morally wrong in anyway, to him it's scrap and $1 is more than they'd get otherwise, you created a win-win by finding it and knowing what it was. But elderly widows should have automatic protection from getting screwed and paying a little old lady $500 for her late husband's classic Vette would be inexcusable.
