The correct answer is "don't play grey knights". What you should do with that $300 is make a taudar army instead.
Grey knights, at the moment, require some amount of thought and skill to play. Thus you will lose more games with them. Thus they're the wrong army for you.
If you insist on spending that money on
GK and nothing else, then I'd highly suggest a change in your attitude towards what you're looking for in an army, as the two are going to be so grossly incompatable that one of the two is going to give out to the other, or you're going to ragequit
40k altogether.
