More fuel for your fire- Not sure about the AV store, but overall, Watson's doesn't exactly have the best reputation in their home turf for customer service.
Also, they may service what they sell, but I'd still want to know why they switch brands around so much. Is it because they are loosing their dealership rights for some reason, or are they just chasing higher profit margins, or what?
In addition to Watson's, check out some other places too, just so you can get a good idea of other spas brands, prices, etc.....
Happy hunting.
