The best mfg of 1911's in my view - is Wilson Combat...( prices start at around $3,000 --- and you can get a very nice gun from Wilson Combat at around $ 3,500 ...like the full sized CQB with some nice options on it - a lifetime warranty for the gun - and a 1" guarantee at 25 yds ). Ed Brown's guns would be a close 2nd to Wilson Combat in my view.....Les Baer or Nighthawk would be a distant 3rd and 4th...( and 5 - 10 ) are Springfield, Kimber, Sig, Colt, etc....
On a budget...the new Colt's are pretty nice guns ...at around $ 900 in my area - but it doesn't have a lot of options on it that most of us want - like an ambi safety, checkered front strap, night sights, etc. / but
Colt is offering them in both 9mm and .45 acp ...and the one's I've seen lately have decent triggers in them.
Springfield's TRP model is also a nice gun ...full sized, ambi safety, mag well, night sights ..for around $ 1,450 in my area. Its one of the guns that would be high on my list as "affordable - with good solid options". The less expensive Springfield Range Officer models..are around $ 900 ...but they lack options and in my area they're coming in with some pretty crummy triggers in them ( lots of slack and creep - and one was breaking at around 8 lbs which is way too heavy in my view ).
Sig Sauer makes a nice 1911...it has a few oddball issues / like the external extractor - and it won't fit a standard 1911 holster - because the shape of the slide is a little non-traditional. Prices are from $1,000 - $ 1,750 or so...but shooters are saying nice things about them.
Kimber makes a lot of guns ....from $ 1,000 - $ 2,750 or so ..../ and internally they are not very impressive....and triggers are often marginal at best...but their upper end models around $2,000 can be decent guns / but probably not better than the Springfield TRP model I mentioned above at $ 1,450 or so.....
Just a note ....but my primary carry gun is a Wilson CQB, 5" gun, in .45 acp...its thin, easy to carry IWB in a good holster with a good belt...and its the gun I shoot the best ! -- so I carry it - but I'm old school....
