Any USA merchants using RBS Worldpay? Your comments?

I notice that my shopping cart supports Worldpay so I’m considering them as an option for merchant account and gateway as they provide both apparently. I could not find any information about pricing on their website however. Does anyone here (USA) use their service? If so, what is your experience?

RBS has a couple different options, depending on your requirements.

My experience with their Global Gateway / Bibit solution isn’t great - it does the job, but it has some limitations that can get annoying, specifically in their admin backend as well as their API’s.
