Welcome to our forum.
I assume this tub will be used indoors or in a very warm enviroment? If you are planning on using the tub outside in the snow, the $$ to heat it will be more money per month than finanancing a higher end unit. Not saying you shouldn't buy a $3000 tub, but you should understand what you are getting and hopefully we can help you understand if it will meet your expectations. What are you using the tub for?
