Have you tried Moneybooker? I have yet to try that securemarket but based on the site itself, it seems pretty new so I dare not comment on the credibility of this site.
For 2CO, people can pay you directly using their credit cards but if u use paypal alternative like "MoneyBookers" people don't have to post their CC details on your site
to use Moneybookers you have to verify your credit card - they will take random amount less than 2$ and you will be asked to tell them what amount they took and your CC will be activated and that small amount won't be lost too - they will add it to your account
guess what? I got problem using moneybooker. They wont' accept my CC. I have heard several people complain about this issue too. Look like the best way to use moneybooker is to use bank transfer.
