1911 doublestack- I'd trust one, and would tend to lean toward Para or STI. But I think the best option for sub-$1K (if you want a heavier, 1911 type steel frame) would be a CZ 97. Great gun. And essentially a double-stack 1911. All it really lacks is the grip safety, and I'll bet it's higher quality than any similarly priced 1911 option.
Other options- The XDm45 is an outstanding gun. I have one and it's my hi-cap 45acp of choice. I've also been impressed with polymer FNs and Sig's alloy P227. There are others that are probably great, but I haven't worked with them enough to offer a meaningful opinion.
