I'm finally tempted to pull the trigger and purchase my first miner. I wanted to start small, but I realised buying a pure SHA2 hasher means I am going to get left behind pretty quickly. For that reason, something that can do scrypt makes more sense. Does that thinking make sense, and if so, do grid seeds still make sense? Some people above say yes, some people say no. I think thats the same for all mining equipment though no?
