Thank you for your quick response. Yeah, advanced was unfamiliar to me as well and have pretty much ruled it out. Another update is yesterday I had Anderson come out and their prices were much higher, their rep was quite adamant that vinyl even if from brand like pella would be cheap/plastic and not a good option for a 3 panel wide door long-term. Once she knew I wasn't quite for Anderson due to the price, before leaving she suggested I go with Marvin Elevate which had got a quote for 5200 from another provider and they are wood with fiberglass on the outside, pine wood on inside. So now I've got to choose for these 4 I suppose: Pella 250, Simonton Inovo, Alside 6100 (Also has wood on top frame), Marvin Elevate.

Pella and Alside would be eliminated immediately form my perspective. Andersen rep, was he pushing the Renewal Line? Elevate is a solid choice in my opinion and considerably better than the others you mentioned imho.

Anderson rep was presenting the vinyl clad with engineering wood inside option. Not sure which specific line it is. She was from Renewal by Anderson. Any particular reasons why you suggest against Pella/Alside - is it the low-end /vinyl part or brands in general?

Would the wood on inside of elevate not be susceptible to rot? also eventually i plan to replace windows and in my budget would very likely be vinyl, will they look really out of place with a wood (painted white) pine patio door? (i dont have windows in that same room, but would be in adjacent/other rooms. for reference i replaced interior doors last year with menards 6 panel wood painted white).

lastly, any thoughts on Marvin essential series (vinyl), likely to be cheaper as well.

sorry for all the follow-ups, there are so many options and not having enough expertise/experience/feedback on who to trust, getting very confusing. glad we have this site with experts like you guys contributing.

"is it the low-end /vinyl part or brands in general?"

Those two brands are at the bottom of the barrel along with many other builder grade products. Marvin Elevate would not be susceptible to rot unless you left the door open wide routinely in the rain and it got wet. As far as vinyl windows and the Eevate door, no issues with the looks as many times the doors and windows are different manufacturers and or series. Also they are two entirely different products regardless. Essential series is all ULTREX (fiberglass) not vinyl and is a good product as well, and less expensive to boot.

for an update here, I have essentially narrowed down to following:

1. Simonton Inovo ~$4000

2. Marvin Essentials ~4100

3. Marvin Elevate ~$5200 (ruling out due to price. place with good financing is saying $6887)

4. Sunrise ~$5456 (again likely ruled out due to price, however, good financing option, curious to know feedback on how much better/worth it may be over the others above).

Secondly, I am also replacing two windows in my kitchen, for which I have estimates of around $600 for Simonton 5500 drop in, or $75 extra with trim. Going to see if any better pricing with Marvin or Sunrise, but likely to go with 5500.

Mohammed N. Would you provide an update and pics of what you chose and the outcome? I am looking for a 3 panel multi-slide patio door system to replace my 35 year old deteriorated wood 8' wide French door/sidelite. With the wisdom of Millworkman, I was narrowing my choices to the Marvin Essentials/Elevate, but throwing in consideration of Western Windows.

Sunrise is the best of that group. what state are you in?

Sometimes that affects what brands are available.

Window genius: Im in Southern California. I’d like all 3 glass panels to slide (triple track), stack in any variation of : all Left, all Right and all center if possible but Id settle on all stack to one side, meaning 1 door is fixed. Threshold does not have to be flush from inside flooring to outside patio (as it is currently)
