I've been told by several people that distributor pricing for FPGAs is ridiculously inflated compared to what direct customers pay, and considering that one can apparently get a dev board on AliExpress for about $110 [1] while Digikey lists the FPGA alone for about $1880 [2], I believe it (this example isn't an UltraScale chip, but it is significantly bigger than the usual low-end Zynq 7000 boards sold to undergrads and tinkerers).
