Those prices you got were probably for completely restored carburetors including correct factory finishes etc. I don't think he does just "rebuilds".

Look on that online auction site...W1's come up on there quite often. Or, place a wanted ad here and buy a couple kits and rebuild them yourself. Make sure you get two matching models.
I think the 574s is a good one if you're putting them on a 235.
