The moonlander looks awesome. The ergodox-ez looks nice as well. I wish there were some cheaper options out there for people who don't know how to solder.
Most of the good ergonomic keyboards are around the same price. Look at this one which it is good, but I personally didn't like: https://kinesis-ergo.com/shop/advantage2/
Basically what put me off was the way the keys are arranged in a semi circle. It was uncomfortable to code. I am not sure if it is because I have big hands or just the design didn't work for me.
You could try Microsoft's ergonomic keyboards, they are cheaper, but I personally didn't like them either: https://www.microsoft.com/accessories/en-us/products/keyboar...
