Its totally up to you.
If the mod is indeed authentic, yes you would be money ahead.
But you would be giving up the better mod IMHO.
The Scottua is a mech hybrid by the looks of it and falls into the Advanced user class.
As in you better know how to build and test coils.
The IPV has a lot of great features and some of them protect you.
The Scottua not so much.
Me, I would stick with the IPV3
Like I said, completely up to you.
