I posted nearly the same question a few days earlier. I did a search on pricegrabber.com and have tentatively decided to purchase from The Digital Megastore. pricegrabber provides user ratings and TDM has very high customer satisfaction. I believer there were something like 220 reviews, most all of them 5 stars. Of the negative ones (9 one stars), when I read their specific complaints, it seemed like they were from customers that were just hard to please. TDM say's that everything is brand new, original factory packaging, and comes complete with full manufacturers USA warranty. I have also contacted Olympus by e-mail about on-line retailers and about TDM in particular and am waiting for a response. If I get one, I will be happy to forward it to you. Anyhow, in the absence of any specific negative comments, and with the prospect of saving $200, I am very much inclined to go that route. I would like to think that the savings is due largely to volume and very low overhead - i.e., like having a wharehouse rather than a store and one that is located in the middle of nowhere with minimal property tax etc. But I could be wrong.
