You must be referring to the Elite VSX-47TX, and the VSX-49TX, which is also available with the I-Link (VSX-49TXI)! An Elite VSX-49 is a much older unit, and does not weigh 63lbs!!!As far as the difference in the units, the VSX-47TX has a more simplified remote, although it does have calibration capabilities, and the VSX-49TX/TXI)- (2 seperate Models), come with a touch screen remote, which retails from Pioneer for about $375+ (For the Remote alone)!! Also, the VSX-49TX has a rigid type side exterior, while the VSX-47TX, has a flat side. Shipping weight IS the SAME!! (63lbs)! As far as shipping is concerned, sellers can make up any price they want to, and cost vary upon the distance that the item has to be shipped, and some will double-box them, as they are extremely heavy and need as much protection as possible the way that carriers handle them, and going through conveyors! What ever you purchase on ebay, especially a high $$ item as these, take out shipping insurance at what ever the cost! On some Ebay listings, the sellers will state in their description, or payment and shipping instructions, that insurance is included in the S&H, but you need to make sure that the small box on the bottom left corner has that in TEXT, as the default setting is NOT OFFERED, but if they do not scroll down that very small drop down box, and make the necessary changes, even if the seller states that it is included, it will not appear on the invoice!! It will have not offered, when you check-out! I would clear this up with the seller, and have him revise, if you have not already purchased, or have them send another invoice, where shipping insurance is documented in the invoice, and payment!! I know this is out of date, but maybe it may help someone else!
