Look in your local area for amateur astronomy clubs. They can arange to get you to some scopes so, you can try different setups before spending a lot of money.
What part of the country are you in?
I’m in SC. I’m barely ambulatory, I can use a walker, cane isn’t enough support, there are other issues that pettywell keep me chair bound, can’t drive being the most restrictive.
Somebody recommended a setup with casters (wheels) which is doable for me, but my preference is a motorized sit down walker with a chair the swivels and locks at 90 deg.
