Looking for a good therapeutic hot tub

We are looking for a hot tub that has good jets for therapeutic massage. Bells and whistles aren't exactly necessary and we don't need anything too big. 4 people.
We are planning to go and look soon but were looking for reviews or experiences others have had. It's all new to us so we want to make sure we are making a good choice!

Thanks :-)

Good luck. There are so many brands and models that it is near impossible to compare between companies. I remember an episode of 'Good Girls' on NBC where they basically say hot tub businesses are a great way to launder money by criminals.
