Carburetor Recommendations

[Organism_ike]

So I've finished up the rebuild of my 305 finally, but now It's time to trash this quadrajet and get a new carb. The quad ran nice and I have it all tuned, but the fuel filter housing is leaking and the throttle shafts are worn so I need to move on. I'm just looking to see what brand and size you guys recommend. I just havn't tried enough carbs to know whats the best run for your money.
I care more about economy than power, but am not trying to build a dog of a motor either. I would think 4 bbl Vacuum Secondaries under 700cfm is probably my best option, but I am leaning toward the Edelbrock performer 600cfm and I don't think its a VS. Want to stay with electric choke. I know many will say buy another quadrajet, but honestly I'm trying to buy a used carb and I can only trust a re-manufactured quadrajet. Also, I'm tired of constantly going back and tuning, and I have heard that Holley's are like that sometimes. I'm not sure how they compare to quadrajets though.
