So I'm sure someone other than me can give you a better recommendation based on experience, but as someone who has struggled to splash out on a keyboard that is more than $10, I have been eyeing a Keychron keyboard lately. They seem to be pretty highly regarded for mechanical keyboard at an entry level price. Check them out.
The C2 is what I've been looking at. Unfortunately if you want backlight they are out at the moment but I think it goes in and out of stock.
