Paypal alternatives

I had a problem with paypal especially they dont have seller protection for digital products. So I looked for alternatives for my website to sell digital products. As usual I googled and found alot of websites providing services among them I prefer few to use.
1. Google checkout.
2. Money Brookers

3 . http://www.propay.com (like a merchant account without all the fees)

4. http://www.bidpay.com (closest competitor to PayPal)

5. http://www.bitpass.com (a little different)

6 . http://www.firepay.com

7. http://www.neteller.com (based in London)

8. http://www.checkfree.com (another popular alternative)
