Is notawheelchair a good choice for affordability?

Hii i'm looking into getting a wheelchair, and im not sure whether or not my insurance will put up a massive fight on allowing me to have one since im thru state insurance

I'm trying to come up with a backup plan so that if its too difficult to get a wheelchair thru insurance that i will at least know where to look so i can work on buying one with the help of friends/family
My friend recommended notawheelchair and i wanted to know if anyone had recommendations on other places to find affordable wheelchairs (I tried checking spinlife but their options for my weight isnt too great since im 280 lbs (i think i only saw one option for rigid wheelchairs)

Also is there any specific recommendations for international travel regarding folding vs rigid wheelchairs? i go between the US and denmark to spend time with my husband while he's at university. im not 100% sure about the difference in performance for those two options
