In my continued search for a 6-7 person spa in the $4-to-$5k price range, I recently came across a used 2003 Hot Spring Grandee in a pretty good shape. The asking price is $3,500; delivery will likely be $500 extra. I have also been contemplating buying a new spa from Costco (e.g. Key West or Elements, when they are back on sale, they will also be around $4k). How do I go about choosing between a 2003 Grandee and 2010 Strong Spa? I am not looking for a gazillion jets, so Strong’s advantage in jet count is not that important for me. But how would these spas compare in other features, reliability, insulation, etc? What else should I take into account before pulling a plug on either? Opinions from folks who faced a similar choice (e.g. higher-end used vs. lower-end new) would be greatly appreciated.
