RAM upgrade options and advice

I'm looking to upgrade the RAM on my Hackintosh from 32GB to 64GB and wondering what the easiest most hassle free way to do this is?

Here is the build details of my Hack. I'm current running 2 x 16GB Crucial Ballistix Sport 2400 MHz DDR4.

I know the easiest(and probably cheapest too) way would be to get hold of another two of these with the exact same spec. I've had a look on ebay and there doesn't seem to be many of them about and you obviously can't get them new any more.

What are my other options? Is there a new 64GB kit I could reasonably expect to work out of the box?

I'm looking for a plug and play option if possible - Since having a daughter I don't have the time any more to tinker with my hack like I one did!
