It seems to have been out for a while. Does anyone have any experience with FPS? I'm launching a new project soon and the one thing left is payment processing.

It seems to have been out for a while. Does anyone have any experience with FPS? I'm launching a new project soon and the one thing left is payment processing. I'm scared to be tied to just PayPal and am looking into Google Checkout and Amazon as well. I know, I know, just get a merchant account. And I will. But this is not really a startup or company and much more of just a small idea I'd like to test out. Ideally, if it picks up steam, I'll switch over to a real merchant account.
