Be weary of those hobbyists you see continually posting things for sale on your local forums. Sometimes these individuals are respectable and just so happen to have a lot of extra stuff laying around. Others, unfortunately, aren’t the stand-up citizens we hope to encounter. They don’t sell equipment that’s in the greatest shape, and it’s something they probably got second hand themselves. Research all buyers and sellers you want to business with, whether they are local or somewhere else in the US. Any respectable seller or buyer will gladly show you some form of feedback.
