I also love to do nursing homes. I don't do many now since I'm working just about every night, but I feel they are by far the easiest jobs in the world. 50s and 60s music are what a great majority of the residents remember and love.
I've been using the Roland E50 far longer than I intended, in fact close to a year now. It's a really good keyboard and very light in weight. I think that even after if and when I get an Audya, I will keep the E50.
