Am a first time buyer looking at smaller units (2-4 person). Cost is a little prohibitive so am looking at used spas from private sellers (craigslist, recycler, etc.). Love the "bang for your buck" factor and desire as much quality as possible rather than be someone's hauling service. Is this more like buying a washing machine than a car? Are there basics to look for and/or steer away from?
For example, a Sundance Tango, 15 years old, needs "control panel", has "new pump/motor, heater and cover".
Tried to find "control panel" parts for Sundance Tango and didn't find a neat fit. How might I assess whether this is a good deal or not before knocking on their door?
Thanks in advance.
