Otherwise Drop, Mechanicalkeyboards, KBDFAN all good stock sets. Do not buy on Amazon Unless you know you want Drop,SP,GMK ETC. Their $10-$20 sets will leave you sorry. Although Amazon does have some good prices on high end sets if they have the set you want. That is not Prime though. Wait 3 weeks. I am too impatient for group buys. I will actually pay for a one off. I understand most would not.
