It looks like both these models are available to me in South Africa.
I want to build up my system over the next five years using one of these models as my building blocks. I want my building blocks to be firmware compatible so I can parallel the units that I buy in future years. The two models are incompatible with each other.
My question is which between these two models is likely to be available for longer?
In other which model is going to be phased out last, so I have a better chance of getting more compatible units in the future?
