Are hot tubs expensive to buy and run? Well yes and no on both counts. You can get a basic hot tub (Cedar barrel hot tub) for around $1,000 or even an inflatable 'Spa 2 Go" (Before you laugh I have one) and to be honest we use our hot tub pretty much everyday of the year and our hot tub still costs us less than $6 a week to run).
That said you can pay $20,000 for a top of the range hot tub, but for that price you'll be getting a hot tub with seating for around eight people, music, underwater lights etc. You can even get hot tubs with built in tv's/dvd's. But me I'd recommend a good old fashioned cedar hot tub as your first hot tub purchase. They're cheap, easy to run - and believe me you want a hot tub that is easy to run and doesn't require hours of maintenance. For more information why not visit Hot Tub Source
