typically, the 1991A1 line is a beginner's gun.
if it's a new colt, the price is acceptable, if not a little high. my 2 cents, others may have other opinions. i'm not a dealer, just a gun nut in texas.
i just traded a 1991A1 commander length in stainless with guide rod and a trigger job for a full length 1911 "loaded" S.A. stainless gun with all the bells and whistles. i traded in a used pistol that i would have had to throw 3-500 at in order to get features i wanted (ambi safety for competition, beavertail, upgraded sights, etc.) i threw in $200 boot, and the dealer went for it at once.
i've done a couple of custom pistols altered by one competent gunsmith, and one not so competent gunsmith. it's kinda like putting $1500 chrome wheels on a used corolla. if i'd have chosen to modify the colt to the level the S.A. was already, it would have cost me a lot more than the $200 i shelled out. i traded a stainless gun and got a stainless gun. i let go of a used pistol and got a new one with a warranty and all the factory paperwork, and didn't have to go to the trouble and expense of making "upgrades".
if you're happy with stock grip safety, single side safe lever, and not so great sights, then you've got an option. shop around. sometimes competitors will have good deals, and in an economy like this, they're hawking wares for sure.
best of luck in your search.
