Air Gap Manifold Opinions

I've heard quite a few "you get what you pay for's". Heard they have thin castings, the extra casting for the dual pattern looks tacky, that they may not seal. Ive also heard they work fine. I, personally, wouldnt run one because of the dual pattern looks pretty tacky, and also I'll pay for the made in the USA edelbrock and support them making new stuff for our engines. Just my 2cents :D
