Nordic -- Spa Models

[NullQwerty]

Hey folks,

My local dealer sells Nordic Spas. I was looking at the following models which all increase in price by around $500 successively.

I was wondering what people's opinions were:
Crown II (circle spa)
Crown XL (circle spa)
Escape Premium
Escape Premium R
Rendezvous Royal

I was leaning towards the Escape Premium, but all are options which is why I'm here.

Thanks!
