Credit Card Merchant, Credit Card Processing Online - Who do you recommend?

Anyone here accepting payments online? What merchant service are you using?
One with easy to implement api? Do not want to see logos of the xyz merchant (example paypal)

Looking for automated approaches.

Appreciate any recommendations..

csb:
For this project, working on a site where we accept payment online but do not want to see the paypal logo or any other logo except the visa,mc amex discover.

Not against paypal per se, and Paypal has an api that allows for no paypal logo I believe, but hearing stories of people locked from their account. I see charge.com has bunch of complaints. Havent really looked at many others.

We have cybersource and Boa merchant services for another business but their api is pretty daunting.. so looking for something clean ,and preferably easy.
