I have an old paddle from my college days from over 10 years ago. It’s starting to show some wear and tear most noticeably on the rubber (scratches, scuffs, etc.) due to poor maintenance and storage over the years.
It depends on how serious of a player you are and how much you plan to be playing – but you could either buy the rubber by itself and resurface your existing paddle (which requires some amount of knowing what you’re doing) or you could go down to your nearest sporting goods store and spend somewhere between $40-60 and get a pretty nice paddle with high enough quality rubber that should last you a good while. The better care you take of the rubber (cleaning it) the longer it should last you.
