We have the MTI caribe air tub. I LOVE it. It was similar in look to the Kohler Sok but less costly. The bubbles are really nice, and I added the in-tub radiant heat system and chromatherapy. The chromatherapy I pretty much never use. The radiant I do, but it takes a while to heat up so unless you remember to turn it on way before you take a bath, there's not really use to it. The air tub system is nice and the tub itself is comfortable. Let me know if you have other questions, I can answer them.

Here is our MTI Caribe tub:

I am considering an MTI Air tub, with the inline heater that heats the water.

Is your Air tub motor noisy or do you just hear the bubble sound?

I am hoping the heater will offset the cold air of the bubbles - any thoughts?
