Hello!
I've gone through this 3 months ago, so i couldn't pass by and not to give you my 2 cents. I bought SaluSpa AirJet. Don't be scared, yes, it's inflatable hot tub. To be fair, I hadn't known that they exist, until we bought one. For me it's good option, because it's compact, movable, lightweight. It was in the backyard, but now it moved to the house. Of course, there are disadvantages too. Inflated hot tubs are said to be not durable. I don't know is this true, but i suppose so. Anyway, for first 3 month everything is perfect. If you still unsure i'll leave this here. It helped me, maybe you'll find it useful too. I dunno which one is the best, as you see i'm not savvy in hot tubs, but we (me and my husband) satisfied with our one.
