Yes, we went with Wells Fargo and they gave us an excellent custom quote (much cheaper than web site suggests). No setup fees, fixed $31/mo and $0.20 per transaction. We have our limit though, and once we exceed it the price will go up.
To enjoy those lower fees we must stay under a certain number of transactions a month and (I believe) we have a max. limit on a transaction amount. I apologize for being unable to give you full details, since my partner is finalizing cost issues with them as I'm typing this.
