As long as the fusion is in full working order AND you get simplify3d with it (it comes with it) and you can knock the price down a bit - it's 3 years old after all.
I'd go for that.
larger print volume, wifi, auto levelling, surprisingly fast.

It all boils down to what condition the fusion is in and how much use it's had.
On the whole - conditional on condition and getting simplify3d - I'd go for the fusion.
