A while back we almost got scamed when purchasing a car that we saw advertized in the newspaper. So I do tell people to be carefull with adds... most are honest but just look for the warning signs and know what you are looking for. I think the same applies to PM..
Also I do know I had a very hard time finding the new member of our family. I really got bogged down with internet adds and just did not know where to go... I think there should be a way for breeders to present themselves. I think in my case there is not a lot a breeders of high quality in my area for what I was looking for and I really got confused. I got lucky, I asked my vet -- at the time I was looking for a small ish shih tuz and he talked me into a yorkie. Best thing that happened... I love my Remy!!!!!!!!
well that is my 2cents!!
