I'm hoping someone can help point me to good motorized wheelchair for a friend who lost her legs. Something that is good value as well as good quality would be great. Thanks in advance.

Bingle could possibly help.

Plenty on Lazada, and I have seen them in Makro.

As said check Lazada/Shopee for units under 20k.  Narrow size is important for use in home so check that.  We got one at about 15k which now about 17-18k but seldom used as patient walking ability returned with medication but does appear to be fine - have not used enough to recommend.  If legs lost perhaps a simple chair version without foot rests would be best and more compact, but as said no expert.
