I need some help to make this decision about baby swing.?

I know each baby is different. This baby is my third child on the way. I had already had a swing but give to my church nursery. It just goes back and forth and boys hardly didn't like it. My first one like the swing that went side to side at my brother house. Right now I am trying to think about buying a new one. I can sell this after I am done with it or give it to my church has well. I don't know if my one I have is still working or anything. Should I go ahead and by a new one so this one would go side to side and back and forth. I am single mom but able to buy a new one since I got my taxes. Planning one to get the rainforest one since it use a plug has well. What you think I should do.
