The plus about the Phatty overdrive is that its setting can be saved with a patch 
one thing to keep in mind is LP2 resale value is poor around USD$800
Voyager RME resale value is around $1500 (You can buy new for around $1800 if you shop around)
Here in the Netherlands resale value is about €850,-.. But on the other hand, why think about this at all, any sane person would keep it
