Hey guys, I've wondered about this for some time now and was hoping you could help me out. I know that many times electronics companies will issue a product with a different number to different sellers (ie. Best Buy vs. your local electronics shop). To use my example. I'm getting ready to purchase a Yamaha CD Player. I have found the unit at Best Buy/Sears and what appears to be the exact same unit at my local shop....but they have differing model numbers. Now the cases look exactly the same...on the yamaha site the product pages for these 2 products are identical (specs, features, etc) with simply the model number being different. Now, are these exactly the same with the model numbers being the only difference? If so, why do companies do this? Thanks Everett By the way, this came up because I found the unit on closeout at Best Buy/Sears but don't want to go that route if there is a quality difference.
