When I purchased my 798 last year, I went ahead and upgraded to the better ducer. Can I say it made a difference, no, but then again I have not seen any images with the stock ducer, nor did I use the standard ducer that came with it. I have been very happy with my unit so far. Yes, the screen is small, but if I see something that I really want to look at, I either zoom in on the object or use an SD card and record and then take it home and watch it on the computer. For the money, I am glad with the purchase, but sure be nice to have a larger screen sometimes.
