Not sure what to do here. I am buying a Mits WS-65819, both Tweeter and Cambride soundworks have these for $3499. I see these same sets on line for $2899. I would love to save myself $600 and buy online, but my worries are that if something goes wrong with the set, who is going to service it? I do plan on buying a service plan, but have heard of so many horror stories of sets being down for weeks and months. Any thoghts from the forum are very welcome, 3 grand is a big deal for me so I want to be sure.
