I want to buy a goog but afraid market will tank when I do.. should I instead put into something cheaper?

I have DCAed QQQ and IWM all the way down.. I have 2k saved and I want to buy a goog but I'm hesitate to spend 2k at once with the market how it is. I'd rather buy a QQQ every couple days. Should I just risk it and drop 2k? Let the 2k sit on the sideline waiting for it to drop more? Or say fk goog and keep DCAing?
