Two Gopro Hero 2 Trade for Hero 4

[Smossy]

2 + 2 = 4?

In alot of instances, two cameras are better than one.. But I lack barely even using one as much as I should be these days.
The 4 has a few better features Id prefer to have over someone who may just want an easy point and shoot camera, or two.
Looking to possibly trade my two perfectly working Hero 2's and some accessories for a Hero 4

If there's no takers Id possibly be willing to swap a Hero 2 for a Hero 3 + $cash$ difference.
