Swings for babies

Ok im a FTM and i wanna buy my little girl (3 weeks) a swing im looking for one that can last me a good time. Idk what stores or websites have good baby swings. I dont plan to use the swing right now cause shes to small but i wanna buy one so she can use it pretty soon. And if i do get one should i buy the regular swings or the ones that are very low and by thay i mean the ones that almost touch the ground? And are swings usedful or no?

Any recommendations or good brands that you have used or like?
