Folding mobility scooter

I am looking for a folding scooter for myself (don’t mind 2nd hand) . I have some use in my left side can anyone suggest which one i should look for.

DeVilbiss Airfold looks good - I have it on my list of possibles. I do already have a rollator by Devillbiss and the engineering quality is good. DeVilbiss are not the cheapest but they do have the quality.
