As said, if stuff is properly listed with prices and with pictures, then people know what is what.

Also, people will tend to act faster, if they need a part and you have it with a price, and it is on a public forum so anyone could snap it up, they will get in quick in most cases.

You can always do a "may be breaking if enough interest with the list as above and see what interest you get.

As for messers, there are always messer, but a clear picture and a price means they buy or they don't no holding or deposit, money sent up front and done on a first come first served basis - you snooze you lose!!
