Note this a re-list of the FS1R posted here.

The price is lower. If you do a quick eBay search for other FS1Rs you'll find that some go for astronomical prices. The reason likely is because the FS1R in incredibly deep offering Yamaha's unique Formant synthesis as well as an 8-Op FM engine. The DX-7 only had 6 Operators. The FS1R can load DX7 patches but it is capable of far more complex sounds. There is also an iPad editor for the FS1R created by yours truly.
