HESITANT with NEW member sellers

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. 

To prequalify any a'phile as such and not a scammer,  I ask the following in no particular order.  How may copies of Kinda Blue do you own?  Just who is Diana Krall really?  Whatcha think is better analog or digital?  Do you or don't you believe in power conditioning?  How do you isolate your cables from touching?  If there is a stumbling on any of these questions, you have a scammer beware!!

Ferrox, wire transfer is probably provides the least ability to recover your money, should the deal go bad.
Paypal, generally sides with the buyer. Though they usually ask you to work out any differences with the seller/buyer directly, before entering into the fray.
As for CC companies, some are better than others. If yours doesn't want to help, then cancel the card and go to another bank. 

I share the general trepidation about zero-feedback sellers, but we all had to start somewhere. One way to establish a good reputation (IMO) is to begin by being a buyer rather than a seller if possible, and showing yourself to be a reliable one. Then, when posting an item for sale, be complete in your description of the item, including your ownership history of it (e.g. are you the original owner or a subsequent one?). Posting stock photos and a copy/paste item description from the manufacturer's website are big red flags to me. If nothing else, it shows me that the seller doesn't care enough about the transaction to expend any time or effort on it and that doesn't boost my confidence.

I agree that starting as a buyer is the best way to accrue good feedback even if it's relatively small items such as cables or accessories. I never trust stock photos and most of the above advice is very good. Bottom line for me is " if for any reason it just doesn't feel right... then let it go". I also only ship CONUS... Anything else gets too complex ... And remember: if you're doing FedEx or UPS discuss AHEAD of time whether buyer wants or doesn't want "Signature required!!!!"... ( I've had to chase packages at "local" pick-up locations that became extremely inconvenient in time and aggravation). Good luck.
