Piano or Organ

I always thinking to get a piano or organ for my children to play at home, but I still never get a chance. I mean I never have to budge to buy for it. There are a lot of pianos and organ that  can choose with like the hammond organ, but I need to save money for it. I want my children to practice playing musical instrument. I know a family that all their kids playing pianos and I like it. They learn to play pianos at home. I think one of my daughter are having interest about music. I cannot wait to buy one someday.
