at the low end, you can build something great for not much more than the cost of switches and keycaps, as long as you have access to a 3d printer (or don't factor that purchase into the cost :P)
but it's a bit of a rabbithole and you may find yourself building more than one
don't forget to account for time spent
- there's plenty of resources there, I don't really have one to link but the info is not hard to find, and you can always ask more specific questions that I could answer
- aliexpress, ebay, plenty of specialty shops
