I too am interested in this. The last bank I worked for had VERY high monthly fees (like over $500/month + per item charges and change order fees)...more to disuade MSBs from opening accounts than to bring in fee income. The bank I am now working for has monthly fees that seem too low (<$20/month + per item + change order fees).
My experience has been a monthly service charge - in the $250.00 range, and all other charges higher than for the non high risk customer. Hard charges such as Returned Item fees are also increased. And a CD collateral is held for Large Item returns/losses.
