Reviews aren't the best mate, but a very small sample size.
If you still wanna buy, Good Guys is even cheaper at $3524.00 after $300 payback via claim. I'm sure even more room to negotiate in store.
I'd still prefer a Sony 85 over this, recently its price went as low to $4.2K, I was able to negotiate it to under $4K including delivery at JB.
