$2580 is not unreasonable, but asd does have a point. We sell Steigerman pianos, and their SU43 console model is an amazing value. It has a firm, responsive action, and a surprisingly (for a 43" piano) rich, resonant sound. As you may know, Steigermans are built in Beijing (Classic series) and in Ningbo (Premium series).
This is not meant to be shameless self-promotion on my part, so I'll add that there are any number of Chinese manufactured pianos you might also want to look at, including Pearl River, Nordiska, Ritmuller, Hallet Davis, Essex, Palatino, Bergmann, et al.
The Samick you looked at is neither Chinese nor Korean-built, to my knowledge, but a product of Indonesia. This isn't a major consideration, but it's worth knowing, as Indonesia's reputation as a piano producer is still in its early stages of development.
I'm curious as to why you preferred the Samick above the Yamaha, Falcone, Hamiltons and DH Baldwins. If you're talking exclusively in terms of the way the piano sounded to you, then by all means buy the Samick. So much of a piano's sound "quality" is based on subjective opinion, that I think it's arrogant for anyone in the piano industry (or any pianist, for that matter) to dictate to a layman what sounds good and what doesn't. In many ways, it's like other forms of beauty...it's in the eyes (and ears) of the beholder.
Remember that when you're ready to buy, and you've made your decision and communicated it unequivocally to the salesman, you are then in a position of power. A customer who says, "Here's my credit card; I'll buy the piano right now if you'll just do this for me..." (another free tuning, split the cost of delivery with me, extend the warranty for another year or two, or shave a bit more off the price) can negotiate much more effectively than the one who is undecided and wavering between several different choices.
