"There is not a person I would rather recommend to someone than you. Boy, if every support person was like you, people would have to learn to speak without curse words, the average blood pressure of users/customers would drop significantly, etc.. I'd be more than happy to talk with any potential users (of TALtech software)."
"In 20 years of technical work, I have been involved with many technical support personnel and you (and TALtech) are the best. Thanks again."
