I have not heard good things about Paypal. There are a lot of stories about people getting ripped off using paypal. And as a seller, it is risky. One scam is to buy something off of Paypal, report it as destroyed, and then ship back worthless material.
Paypal returns money to fraud victim, sends him to collections:http://consumerist.com/5041902/paypal-refunds-50-defraud-sic...
Customer gets billed twice, Paypal does nothing:http://consumerist.com/5048218/blockbuster-double-dips-in-pa...

So basically, I trust my bank's customer service, and I don't trust Paypal's customer service. So I view Paypal as a potential headache if I have a problem with a purchase. I have generally had good experiences with Amazon, so there is no negative association with that brand, but I don't feel like I really need more protection than my bank gives me.
You may buy through Paypal; but, most buyers don't.
I am very interested in any metrics that show using a well known branding like PayPal, Amazon, Google, etc.. gets less transactions than having your own Vias/MC gateway.
Are there any metrics showing my intuition is not correct?
