Yea I am not exactly willing to have the extra tax liability from a new piece of gear, nor lose the options that the item was sent came with.
The newest comparable model of the piece of gear that keysight wants doesn't even have a price listed on their site, and I am fairly confident that I got a pretty good deal on my item. It is not a spectrum analyzer or a simple DMM. So they are in quite a pickle if they really want to make me whole. As I said before, the item that I have is worth much more to me than the money that I paid for it, and if I were to respond, it wouldn't be without getting in touch with a lawyer on my side, because I don't really care for the legal advice offered by those in this thread.
