help me decide bw 2 merchant account providers?

veryintrigued asked:


I am setting up to accept credit card payments. I narrowed down to 2 providers, AMS (advanced merchant svcs), OR paynet systems.

Thay both seem ok, paynet being cheaper, but AMS having authorize.net gateway for free (which I could use with an online shopping cart).
Anyone had any experience with either?
I would appreciate your sincere opinion. Thanks!
