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

I can't let a topic like this pass by without mentioning commercial (often obsolete) FPGA-based products that are repurposed as development boards. They usually offer FPGAs with much higher capacity for rock bottom eBay prices. * Pano Logic G1 board: https://github.com/tomverbeure/panologic * Pano Logic G2 board: https://github.com/tomverbeure/panologic-g2 * Colorlight 5A-75B: https://github.com/q3k/chubby75 * Cisco HWIC-3G-CDMA: https://github.com/tomverbeure/cisco-hwic-3g-cdma Playing with these has been a fun hobby of mine and while I have a box full of 'real' development boards, I usually find myself going back to the Cisco board for my personal projects.

2x more resources compared to $30 https://github.com/q3k/chubby75 at 5x the price

This LED panel controller can be found for $15 on AliExpress: https://github.com/q3k/chubby75. It has a pretty decent Spartan 6. Your best choice if you want current commercial availability. The eeColor Color3 can still be bought on Amazon for $20. https://github.com/tomverbeure/color3. It has a very nice Cyclone IV FPGA and is perfect for HDMI video. It was very popular for a while for bitcoin mining because you could get it for $20... with a $20 rebate! (https://www.amazon.com/Color3-Advanced-Processing-Device-010...)
