Well, the answer is technically, yes there is one. Let me explain....
Basically, I am able to get the LG BP50NB40 in Australia, then cross-flash it to be a BP60NB10 using my hybrid firmware. I simply haven't added this drive to my list as it is very rarely asked for and it is not as good as a BU40N.
Maybe I will add it to my list, at least temporarily, to see if there are many (any) takers...
As I said, I can get them and they are a bit cheaper than a BU40N. If you would like a quote, please email me: martymcnuts@outlook.com
