First you need to decide whether you want wood, vinyl, fiberglass, aluminum or a composite.

Don't know if I'm too late to be of any use -- we live in NVa, and used Hodges (Falls Church) for a replacement French door ten years ago. They have been absolutely terrific on all aspects of the process: informative, no-pressure sale, great handling of a mix-up in the order (door came unprimed when it had been ordered primed; they primed it onsite for a faster install rather than wait for a replacement, having asked which option I preferred), and great ongoing service -- they have come out twice to fix the screens and double-check the locking mechanism, always for free and never asking to see the original receipt or anything. I highly recommend them. (and no, I'm not in any way affiliated with them, I just think they're a really good, old-fashioned-service firm) But they don't carry all brands, so if you know you want Marvins, for example, I think you'd have to go elsewhere.

So, they ordered the door incorrectly, have had to come out twice to fix the screens and also the locking mechanism and you highly recommend them?

I don't like to encourage Sky's sometimes acerbic sense of humor but that is pretty funny.

Made me smile, too -- but in explanation: they showed me the order and it was correct; it was Norco that messed up (and they admitted it) on the original order. The screens were pushed out of their rim twice in ten years by my son, once as a toddler and once at age 4 when he was "testing" (putting all his weight on) them. The lock needed to be tweaked once, a fifteen-minute job. Maybe I'm too forgiving, but those seemed like reasonable things to go "wrong," and I thought the local company handled the issues promptly and well. That gets a recommendation from me. (At least I gave full disclosure of what constituted good service in my opinion, right? Viennamommy is free to disagree and cross them off her list...)

Heh, heh... Hodges has a pretty good reputation and they have been around for a long time. I would have no problem recommending them either.
