For me, I'm only messing around. I never looked at the Optima and the Piper was sitting next to my tub, I wasn't going to pay $10K for any tub.
I really think these threads get WAY too serious for what we're talking about. They all "copy" each other and the idea is to find the "best" tub for ourselves reguardless what anyone else thinks.
If someone is happy with a Walmart tub, then who am I or anyone else to say it's crap! Did I buy such a tub - no but I didn't buy a "top of the line", "super deluxe", bestest spa either - to me there ain't no such bird - Remember if you paid $3000 or $13,000 - they make hot water and have jets.
Now if someone complains about breaking down a lot or power consumption, then it could be suspect to the type of spa they bought but as we see here - ALL spas might have problems!
Think about it!
