E4xxx series are Allendale/Conroe C2D's.. CPU-z sometimes reads as Conroe..
E2xxx series are Pentiums.. So are some lower end E-models...
From what I was told, the name in this case has little to do with it.. Still the same architechture as C2D's.. IDK, it's been a while since I've thought about 65nm chips..
He wasn't asking you to buy it, he was asking what price should it sell for..
No more than $45 shipped IMO.. Best C2D budget chip back in the day.. Got mine to OC 100% over stock..
