I can answer no two as there is a really good way of trying an inflatable tub rather than invest in thousands. If you really get into using a tub then you can get a proper one but this has really been a good buy for us.
We got one of these three years ago and love it .
It is easy to set up and maintain. For the money I think they are excellent value for money.
I would also invest in a good net and also a spa vacuum

Worth every penny in our experience.
We still haven't justified getting a real tub yet.
