DE10-Nano used to be ~$100 2 years ago before FPGA vendors decided to stop manufacturing while bumping prices.
$30 is a good price for FPGA dev board, requires a little creativity https://github.com/q3k/chubby75/tree/master
Interfacing FPGA with Ethernet PHY over RGMII

I am now trying to make use of the on-board Ethernet PHYs, which on my revision of the board are Realtek RTL8211FD chips. More details on the board V8.0 revision here. And the Realtek datasheet is here.

Driving large RGB LED matrices

Rather than designing your own PCB, I suggest that you use a ColorLight 5A-75 LED driver board. These are commercial boards that are designed to drive LED panels. They contains Lattice ECP5 FPGAs and have been completely reverse engineered for hobby use. They are very cheap, around $20 on AliExpress.

I use this project https://github.com/NiklasFauth/colorlight-led-cube and it works quite well. I only changed the panel resolution to 32x64. The board uses a Lattice ECP5 FPGA.
