Moving back to the topic...
@zeric, I am surprised no one has mentioned about going solar or going for coins with POS... You can check out "
CrazyDanes" Solar mining
thread for more information. I believe a pretty decent Solar farm can be set up with around $30K-$40K budget. As long as you don't have to pay up for energy, you will always be in the ''Green'. Also, I will recommend you to look into ZenCash's Secure Nodes and superNodes. Could be a much better alternative than mining.
Initially I was planning on a 50/50 GPU/ASIC split, but as the marked looks a full ASIC focus seems the obvious choice to me.
I dunno how you reached to this conclusion, But Getting GPUs is a far better choice than going the ASIC route. There are multiple factors here, Like E.g Warranty. Most ASICs cover around only 180 days of warranty, Plus their resale value is shit. Just look at VoskCoin's recent review about Mining in general, the dude got an L3 miner for around 1600 bucks and a year later it's selling on eBay for around only 150. He only made his money back via Selling it 3x the price due to Bitmain not pumping out enough miners. While a rig of GTX 1080 Tis is still holding up its value. So when you say its an obvious choice I don't know what factors you are taking into account.
