My first tub was a nordic, and it had only a few jets and I had a ball with it. Hot swirling water and a decent sized jet on my back was great. Add a few friends, and a cold beer and it's a real nice time.
So, yes, you can have a great expereince in a tub with a few jets. Most of your hot tubs in the resorts only have a few jets. However, It can't compare to the more exspesive tubs.
how are you planning on using this tub? (year round, seasional, how often? inside, outside?). I don't think you can have the jets and the heater on at the same time with a 110v tub. The insulaiton and cost to keep this tub up to temp would be a concern.
Can you wet test the tub?
The things let drove me away from my used low end tub was heating costs, filtration, noise, comfort, realiability....
What are your expectations for this tub?
