Merchant banking fees, shopping for new provider

[soopermark]

Hello,

I have been with my current merchant bank for 8 years, processing about $500,000 per year in transactions averaging about $40. They have various fees and I've been sharpening my pencil lately, discovering that I've been getting overcharged.

I think I will switch merchant services providers, something of course I am not pleased about but I need to shop around. I have a stellar record with my current bank, for example about 2 chargebacks per year out of tens of thousands of transactions. The chargebacks even 2, are always just misunderstandings and no fraud. I deserve the best rate, at least in my opinion. What kind of rates do you all get, and what should I look out for in shopping around? Any particular banks you recommend are highly appreciated.
