Antminer R4 worth it?

[thesavoyard]

The 6th batch is being sold and I'm worried it will not ROI before it becomes obsolete. But with BitcoinCash, The difficulty might drop for a bit. Plus there are other SHA-256 coins that can be mined. It's not a bad price to have a decent miner. What's the consensus?


Edit: nevermind, it's not available. On their site, it didn't say sold out on the products page....
