I think I'll be dropping mine - I have the same $10/mo rate but a good 90+% of my customers would rather write a check - out of the checks i've only had one "bad" one and they cleared it up in cash shortly after (the IRS had frozen their accounts)
You may be missing the real value of accepting credit cards, customers will tend to have more work done, when they find out you accept them. it can increase you business, and your income.
