Options are a ton
Any of the following manufacturers have models in your price range.
Kimber
Springfield
Rock Island Armory
Taurus
My personal preference is the Kimber Custom II (but that is strictly personal preference, any of the above will give you a good gun)
Look around at the different features that each offer and decide which look good to you.
I envy you getting to go gun shopping
Make sure to post (with pics) which ever you buy.
Does your budget include the costs for holsters, magazines, magazine holders, practice ammo to learn your new gun?
If you need to cover all that with your $700, I would suggest a Rock Island Armory Tactical model. If that money is just for the gun, the Springfield Mil-spec is prettier, though I've got no first hand experience with the Springer. The Rocks, though, I do have first hand experience with, and they have all impressed me big time. Very accurate, very dependable, they are functionally fine guns.
Kimber doesn't have a custom gun shop. Their "Custom" marked pistols aren't hand fit like a Wilson and roll off the same assembly line as all of the other Kimber pistols out there. The only difference is they get a fancy roll mark that says "Custom Shop"... which unfortunately is misleading.I own a Kimber 1911, Crimson Trace Pro Carry II, its got bells and whistles on it which are not really necessary for you, but Kimber is your manufacture if you are looking for custom 1911...they are pricy, but not like Wilson Combat.

Their "custom" work consists of finish differences, different sights, grips, and other drop in/bolt on parts. If you think they have a real custom shop, call them up and ask for a custom slide/barrel length. Ask them to put 20LPI checkering on their front strap (or better yet, on the rear of the slide). They will tell you they don't provide such services.
Kimber and Wilson Combat are nothing alike. Wilson Combat is a real custom gun maker where every single pistol they sell is touched by a highly qualified world class gunsmith.
The same is true for upper end Springfields. Springfield also operates a real custom gun shop where you can order anything you can dream up, for a price... and it's expensive.
I'm not bagging on Kimber, I just wanted to clear the air about their "custom shop".
