Mark,
We are on our second spa from Islander Spas. We had a 7 ft spa before and traded in for the 9000 3 years ago. We love the neck massager and the fantasy lighting. Both times we looked around at all the other spas and chose Islander. I really like the way they are built with the full foam insulation and a maintenance free cabinet. We got the rollassage the first spa but decided not to do that option on the second one. Our electric bill appears to be around $15 dollars a month to run the spa. We have had only 2 or 3 service calls on both tubs total and they were for minor repairs that were taken care of on time. I was just in their showroom 2 weeks ago and seen the new models that I really like! Might have to trade again in a year or two. Hope this helps. Im sure you will love soaking no matter what you buy but we love ours!
