Some things to think about before you take the plunge. Yes, they are great for sore muscles, sore backs and general relaxation. Love ours.
However.
Think about where you put it and what will hold it up. Will it need reinforcing? Will it need to be levelled? If it is full sun then it will beat the hell out of your cover. Will you use it in winter if there is snow on the ground? Is it sheltered from wind?
How will you get power to it? If you have a 'plug and play' version which just hooks up to regular 120V, not much of an issue. If you are wiring 220V to it, you need to plan ahead as that power line is expensive and you may be needing an electrician.
What building codes will apply? Is there a separate one for hot tubs or do you have to comply with pool codes? Mandatory looking into beforehand.
Maintenance is generally adding chemicals or enzymes or salt, and changing filters. Each one has +/-/$.
We change water in our Jacuzzi 2 times a year, but we use it a lot, especially over winter. Spring and fall.
If you keep it for a number of years, things start to go. I've replaced one pump because of a leaking seal, and heaters twice now. Basic electrical/plumbing capabilities.
All this^^^
We just disposed of our first tub, got just over 10 years before it started really acting up. It was beginning to nickel and dime us to death so I sent it on down the road.
It was the standard 120, so you couldn't run both the pumps and heater together.
probably go the route you mentioned[Coleman etc] if we replace it.
