What the options that I should definitely look at? I was a bit surprised to find out that there are so many and I don't know how to make choice because I know nothing about hot tubs. Can't even decide what price range should I pay more attention to.

So, many people know little about hot tubes when they decided to buy it. From my experience, I can say that you definitely should pay attention to hot tube covers and I advise you to check this out because you can find there good descriptions and goods.
