For the doors themselves, it's probably cheaper to go back to the manufacturer and buy new door panels that meet the current frame with the most current insulated glass in them. You just unhinge the current panel and slip in the new panel. Typically the frame and panel are each about half the total cost of a door/frame unit, so it won't be cheap, but it will take zero labor because the frame stays in place.

Actually, you can probably order replacement sidelights too. Just pop out the old units and pop in the new upgrades. You can do it yourself. The advantage of using a new panel or sidelight is that you have virtually no labor to complete the replacement.

If your original manufacturer doesn't have a drop-in replacement door panel or sidelights, look at Marvin Window's custom-sized product and see if they can make a drop-in replacement for you. The key is that if you can avoid replacing the frame that's attached to your rough opening you'll save a ton on both product and installation, and if you can replace the panel or lites alone, labor will be minimal and you'll have a brand new door combination.
