You might post this in the window forum as there are more people there who can offer advice on this topic (myself included). However you need to help us to help you which means provide a little more detail other than just Pella, what your looking to accomplish with these doors? What material you would like to use, ie how the finished product will look? Do you want wood interior, aluminum clad or fiberglass exterior? Vinyl?

DH and I installed to Pella french outswing doors several years ago. They also have blinds between the glass. They are clad on the outside but we opted for unfinished on the inside so we could more closely match our existing stain. Installation by professional installers was a nightmare. We couldn't lock the doors at all. The worst of our issues was Pella's non customer service. It took probably eight months or more for them to finally resolve all issues. It was so frustrating and also unsafe to not be able to lock our doors.
Our house is extremely square so that wasn't the problem. We are pleased though with the appearance and now that they lock we like them.

We want to do a triple door on the front of our home with one stationary door and two out swing doors but hubby said there is no way we will do Pella again not even if they were free. I will be looking for a different door manufacturer as soon as my kitchen/dining/living room project is finished.

Good luck with your quest for the perfect door for you!
