My local Bunnings (hardware store) were selling "grabbers" pretty darn cheap. Also enquire at your pharmacy for places that sell mobility aids and things, they can have some pretty neat stuff that is cool for mobile people too, like the time I dropped my sunnies in the fish pond and used mum's grabber to get them out.

Also my Dad has a portable shower bench on permanent loan from the hospital that he sits on to shower in. Although plastic chairs work well too.
