HESITANT with NEW member sellers

I won't do business with new members unless they are a Nigerian Prince....

often they will offer you to marry his/her daughter and send her some money for visa and plane ticket.

Agreed a certified Paypal member and I ask them for a phone number ,
Or st least call me . Where are they shippjng from their Zip code
And their name before sale. If they will not cooperate move on 
That is a red flag  in itself. If you are that private or paranoid uou should give it to a friend or audio store to sell. Also ask for yhe Serial number and exact model the company will confirm or 
Not the Number. Pictures from top front back  close ups very usefull. Myself doing this for well over 30 years know 
No matter what you do ,it may not be good enough and some
Expect excellent as Flawless  and do look with magnification. 
Yes their are nuts in the pack . Be reasonable and follow good trade points and suggestions. Best of luck  !!

The same stuff happens on the high end watch forums. So, if there is a high priced, well desired item; scammers will always be near.
OP- all the advice you have received is good. Use your best judgement, and remember that item will always be sold again.

Looks like I would be an easy target then. Every time I make payment via paypal charged to my credit card, there will be a short message from credit card provider notifying certain transaction occured. If I don't recognize it, I will have to respond to that message calling the credit card company.

If bad things happen, I really doubt the credit card company would help me charge paypal back for the refund. 

My experience with paypal charged through my credit card was, both of them provided no solution. Paypal directed me to work it out with the seller. Credit card company denied to help because I hadn't reported that transaction as suspicious in the first place.

So I ended up making transaction through wire transfer especially when the nominal exceeds my credit card limit.
