There's this $10 board on Aliexpress called Milk-V Duo S. It's been popping up on my recs every now and then. Looks interesting.

Taken directly from its description:

>Milk-V Duo S is an upgraded model of Duo with an upgraded SG2000 master with a larger 512MB RAM and extended IO capability

>Onboard WI-FI6/BT5(Model Milk-V-Duo-S-512M-Basic/Milk-V-Duo-S-512M-eMMC does not have this function)

>USB 2.0 HOST port

>100 Mbps Ethernet Portwith PoE Support (via PoE HAT)

>Dual MIPI CSI with ISP

>The device also supports switch between RISC-V and ARM boot via a switch

I think there are dozens of boards by now, but what I found interesting and pledged to is this:

I don't have a first version visionfive2 myself, but i heard good things about it and the eco-system sounds like it's growing. There are still rough edges. Lets hope they ship soon (tm)

Edit: What I currently have for my personal projects is a PolarFire SoC Discovery Kit. That's a quad-core RISC-V system with FPGA embedded. Maybe too expensive and not for everyone (130 bucks, fun fact: The dev board is cheaper than the chip itself).

Also the microchip documentation, toolchain and so forth feel really crappy and old, but once you get used to it, it's not that bad and actually getting to run bare-metal risc-v code is easy. There are easy examples for linux and bare-metal

Maybe just run an emulator on your x86/apple, for now? It'll probably be faster than actual hardware, and it will for sure be faster to develop a kernel with.

Thank you all for your excellent responses. No thanks to the fools who downvoted this.
