After doing a search on the Internet for information about spas I found Gene’s Site and ordered just to see if building our own spa would be an option. After reading through it did seem like this could be a good option for getting a better spa at a price we could afford. It is very complete and easy to understand. When ever I sent an email to Gene with a question he was fast to reply with an answer. We are very happy with our completed spa it is far better than anything we could have bought for more than twice the price.
