Remanufactured carbs any good?

Any imput on a replacement carb?
I've got one on the 64 right now. 2bbl. Couldn't find a good core fore about a year. Found one on Ebay, put it on ran better, sent original to Chicago via local parts store. 10 days, $160.00. Git it back put it on, never adjusted, runs like new! Core back on my shelf for later use!
Son bought a rebuilt 1 bbl from Autozone. It had the same box from Chicago. Same story. He's still driving it. Saw him going up the hill the other day.
