Don't worry about the dealer. Narrow down the tub you like, price, and what you get for your money.
Cookie,
I am not a dealer just a hot tub owner.
In my opinion the relationship you have with your dealer is very important.
1)I don,t want to give just anyone my money
2)this is the person to help with financing(if applicable)
3)this is probably where you will buy your chemicals
4)its the first person you contact if you have warranty issues
5)you will probably deal with them about water quality issues as well as this forum
6)installation
There are alot of other reasons but that seems to be my top 6.
