"What is the best entry-level custom keyboard" is a question you will hardly find a definitive answer for. Most people would say that the KBDFans TOFU with a DZ60RGB PCB is your thing, because it's available and cheap. However today we have better options like the NK65 entry edition and the Rama Kara, which are wonderful for their price.I really recommend the former, it's a steal for the price and it is able to get you into the keyboard scene at a price that you can spend without breaking the piggybang.
