Hi Michael,
I've bought and sold several things on this forum. On every transaction I have felt like I've made a friend, it goes without saying, never been shafted.
When selling, on items say <100.00, I like to make it as easy as possible for the buyer. On larger items a money order is the safest bet. When buying, I always do what ever the buyer feels most comfortable with, even when it involves the dreaded PO!
