Ok, my wife has some medical issues and were told a hot tub could be good for her muscles and joints. I started doing some research today and am way out of my depth! We are looking for something that seats 4-6, probably with a lounger. I have no clue what is good in terms of how many jets it should have or anything like that. I know we want it to sit on our patio so not in ground. I haven't even found prices on a lot of websites. Everyone wants to send you catalogs and stuff so not even sure of prices or anything. I'm not sure if we should look for a used one or brand new. Very confused. Help????
