They're a very regional brand that hasn't been around for a long time. Made in the Woodburn area where American Spas used to be made. From what I have heard American Spas had some tax issues around 2000 and was forced to close. I'm not sure if it's some of the same people involved in both companies, but I would assume their is some connection given that they have the same factory address.
They've got spas with a lot of jets and features for cheap, but that's about it. I think there are some much better options in the Portland area. Have you checked out Marquis and Oregon Hot Tub dealerships? They will most likely be more expensive but you get what you pay for. I live in the Portland area and can help you get a deal on a Marquis if you're interested in checking them out.
