carb replacement suggestions

i have a 1973 dodge dart with a mildly built 360(bored to 380). I currently have a thermoquad(6-2363), with a cracked main body and a leaky fuel well. i need to replace it and i was wondering what to get. i want a 800 cfm spread bore(like my old one). The two i was looking at were a summit re-manufactured thermoquad, but i dont want to be reposting this thread in 5 years so i was wondering if they are durable and run well. I was also looking at the JET streetmaster quadrajet stage 1. Those are the only 800cfm spread bores i could find. The quadrajet is $80 more, i am 16 and have some money to spend but i dont want to spend all of it so try to keep suggestions under $500. So in short, what carb should i get to replace my old thermoquad?

Thanks
