I ran into this problem when I wanted to buy a Samsung 900NF. NO ONE, even the big chains had one. I ended up going to a Best Buy, and looking at their lower model; the 955DF. I thought it had the best display of ALL the monitors they had, so I took a small chance and ordered it online.
Outpost.com was where I bought mine, and it was a good experience. They had it for $399, and with 2nd DAY AIR shipping, it came to $409. They called me to let me know that they were backordered, and expected it in 5-6 days. 3 days later it arrived, and even sooner than they expected. Cool.
It seems that consumers are more willing to buy the cheapo monitors, and stores can't or won't pay to have the really nice ones. I would, if I had a store, because I prefer quality to price, within reason.
