What I always recommend is pay attention to the sight dovetails and the grip safety.
Most folks don't understand not all 1911 sight dovetails are the same. If you want a particular type of sight, night sights or adjustable sights, different dovetails will give you different options, and not all options will be available for all dovetails. This from Kensight will show some common dovetails.

Not all grip safeties are beavertail grip safeties, and not all grip safeties will fit on all frames.
If you choose wrong on either of these choices, you're going to spend a lot of time, effort, and money fixing your choices.
I point this out, since when you are talking in this price range, you're going to get a lot of recommendations for the RIA GI gun

This gun will fit your price range, but it will have little GI sights, and a GI grip safety. If you like those, great, but if you want night sights or adjustable sights, or you really need to have a beavertail grip safety for comfort, replacing the stock parts for what you want will often be difficult and expensive.
Spending a little more for something like this
