Hi,
I've been playing with the demo and now want to buy.
Cadwax in the UK are selling MOI3D commercial for £225. This is cheaper than buying it direct, which is closer to £290.

My questions -

Is Cadwax legit and will I get a full version of MOI3D & will I be eligible for free upgrade to V4 ?

Cheers.
