Easiest thing to do is only accept MO's or Cashiers Ck's, unless you know the member pretty well.
There are quite a few people I've taken personal ck's from because I've known them on the forum for years. Sometimes I even ship their stuff before the check arrives. Usually I never wait for those ck's to clear before shipping. It really isn't hard to know when you're dealing with someone whose word is their bond.
But with really expensive stuff and/or someone I don't know well, it's wisest to get a Postal Money Order/Cashiers Ck...
