The original tub I was looking at was the Emerald Cygnus 7009 2004 model and it was a nice tub. They added more jets for the 2005 model year and it was too weak IMO. They also changed the warranty for their Cygnus line to 5 years parts & labor from 3 years but look at the warranty - the wording in it states that the consumer is to pay for shipping for the parts.
They are changing the plumbing configuration on the 2 pump systems (I think the Cassic, Elite and Cygnus lines are 2 pumps) and the dealers should be getting them soon.
I will say they have excellent customer service - I emailed them with a lot of questions and they promptly got back to me. They seem to be a good value tub. The people who have them (when I was researching that tub) all had good things to say about them.
I probably would have bought it if they left the jet configuration alone and if the warranty wasn't worded where the consumer has to pay for parts shipping.
If you have any other questions, I'll try to answer them.
