I just found out that Tweeter is selling all Mits products at a 10% discount on 5/21 and 5/22. The WS-65907 will cost $4500 and the WS-65857 will cost $3780. Is the 907 worth the additional cost? I have seen several postings regarding screen issues with the 907, should I be concerned? I am moving to the Baltimore area so if anyone knows of any other stores to contact please let me know. I did find lower pricing from MyDigitalUniverse.com ($3899) and LetsGoDigital ($3850) by I am concerned about the stability of mail order companies. Please provide me with your thoughts and recommendations. In addition, what should I do about extended warranties?
