If I were you, I'd take the horror stories with a grain of salt. I've been using PayPal for years with 0 issues.
I've recently started using GC and after reading their horror stories, I'm very concerned.
Namely, GC does not offer any phone support or email contact, whatsoever.
Do a google search for "google checkout merchant forum" and read around.
I'm looking into Amazon payments which seems to be pretty equivalent, and I trust the hell out of Amazon (because they have phone support and what not, and I've worked with them for years too without hassle).
Remember, as opposed to all these other companies, Google Checkout specifically, in their terms of service, declare that they can withdraw funds from your bank account if they need to. be weary of this, given that you cannot contact them.
