Paypal is owned by eBay. You'll get about the same level of support from either of them. Your best protection is your credit card provider (never give out your bank routing info to ebay/paypal). If you holler FRAUD, your CC company will back you even if the others don't. Never pay a CC bill in full if you haven't received the merchandise (there are some minor exceptions to this, eg ordering from Asia, etc).
(you might want to turn off your CAPS KEY as a lot of folks wont read an all caps post; its considered shouting in the realm of internet etiquette.)
