I think that it is absolutely possible to say that it's a good time now to do that, especially if you buy it with cash. Market is at the very low point now and in future ETHs price may grow greatly.
For the last week, the price of Gaza showed another maximum of more than $ 3. Of course, this is a very promising indicator for the etherium. I think that in the near future the etherium will take new positions among the crypto currency.
