I'm sure there are many posts like this, but here are my questions to you experts coming from a newbie: What would be my best options for a simple 5 person portable/all in one hot tub? Don't need the fancy features, but would like it to have good space/leg room for 5 (or even 6 folks), to be deep enough, with average number of jets, average upkeep. Not looking to spend a bunch of dough, figured it would cost about $5k, but is this realistic? Should I look on Craigslist for used? This option worries me. Has anyone here bought a used hot tub with success? I don't want to walk into a dealer and try and get up-sold on things I don't need. Just want to keep it simple. Thanks for your time.
