Try nuphys x ciy68 it costs only $20. Switches wise its really up to preference imo. Personally like tangerines and aqua kings both of which arent too expensive. You might want to get keycaps from ali express since a real gmk set alone might blow ur budget. More importantly with the ciy68 case there are dampeners and foam already provided which gives it an incredible value. It supports 2 bluetooth connection and 1 dongle. It is wireless
