With brands like keychron and ducky now providing hotswap options on Q1 or Ducky 3 entering custom builds became a lot easier as these provide big runs which allow you to buy from a shop rather than joining limited group buys with nowadays 6-12 months lead times (and selling out in minutes or taking raffles). It isn't the quality of say Monokei, TGR or Keycult but that is expected for the budget range they play.
Having gone beyond entry market years back I'd say it today still brings me the most joy of any hardware upgrades I make to my computer setup. Walking up to my desk seeing a full custom is something I like.
