"Do you guys really argue with a customer who wants a Cat6 run because Cat5e is 5 dollars cheaper??"

No, but I do try my best to not get customers to use cat6 for voice just because it's on a spec sheet, the same spec sheet that often says "cat3 100pr from IDF to MDF".

"There really isn’t a cost argument between Cat5e and Cat6 anymore. "

takes considerably more time for me to terminate, and when there are hundreds of long runs of POTS, cat6 adds up. Last time I checked, a cat6 110 block costs about 10x what a cat5e does. Keystones (quality ones) are 2x as much, and good patch panels in cat6 are a lot more than cat5e. I can pipe a building in ENT and install cat5e for not much more than what nice cat6 everything costs.
