Finally made the purchase of an Optima. Firstly, thanks to all in this group. Helped me in choosing the best tub for me! After many months of research, wet testing and negotiating, we purchased the Optima and are waiting delivery. We are extremely happy with our decision and can't wait for the tub to arrive.
Best piece of advice from this forum, do your homework and wet test. We had our minds set on another tub, however after wet testing, realised it was't comfortable for us. Also, make sure you get to know your dealer. Our Sundance dealer is exceptional and was the deciding factor in the end.
If anyone is in the Ottawa, Ontario area and wants more detailed information, feel free to PM me.
Now to start researching chemicals and maintenance issues!!
