I have an Arria 10 SoC dev board (not the PCI one, the stand alone version). It's a very complex and fully featured board, it's just not just a "breakout board" for the FPGA. It's also clearly aimed at companies looking to integrate an Arria 10 into their designs, not hobbyists looking for a cheap FPGA board and the pricing reflects that.
