No More Checks?

We have some less than scrupulous individuals in our territory, <gasp> and I am considering instituting a "no checks" policy here. Bad check fees, non collectables and NSF/closed accounts are killing me! OK, I really don't take many in now; most are debit cards and credit cards, so I really don't think the change will be a huge factor.
I was thinking of posting something at the cashiers window and service consultants workstations stating as of 1-1-04 we will no longer be accepting personal checks.
If I go this route, what are your thoughts as to repercussions etc?
