The hubby has wanted a hot tub for years and we are finally ready to make the purchase! I'm excited but overwhelmed. The goal is to start out affordable to make sure we will use it as much as we think we will. We are a family of four. Also, my husband is 6'5 and I'm only 5'3 so my question is- can someone give me their more experienced opinion on which hot tub to buy? New or used? Plug in or hardwire? Size? My goodness they're are too many choices!!!
