I've seen nothing in the sub-$700 category for 4K. There is little at or around $1,000 which I would consider all that good. I kind of think of the Epson 3200 as the baseline product I would use for 4K and would prefer to see the 3800 from Epson instead. Then the X3000i from BenQ.
There are models, like the BenQ TK700STi, which are around $1,500, and are decent.
But, when you start basing expectations on price, at this point, the cheapest 4K models only deliver two which are under $1,000. Of the two listed, I'd probably take the Viewsonic, but I wouldn't spend my money on either. Instead, I'd get the HT2050a from BenQ and get proven reliability and performance and then start saving up for what I really would want... which would be a JVC.
This is the list sorted for 4K by price, keeping things under $1,500...
