Welcome to our forum.
merlot, you are dealing with a personal decision here and only you know the facts regarding the condition and history of these spas. Make the decision that is best for you. There is no way we can interpret the decision you are confronted with.The way you pose the question is a little strange, you seem to be willing to throw caution to the wind, but yet you are not that concerned about buying 2 used spas that are relatively new??? and yet without arranty???IF you are going to spend $8,000, why not buy new, and why don't you have "other" options for the amount of money you are willing to spend?What else are you looking at, or what have you looked at and how long have you been shopping?
If I can ask, how much did you pay for your summit? (please let me know the currency as well)
the warranty on paper is just as good as anyone's but we've only had ours for a couple of weeks.
of coarse people will slam gc but not artic.
