Which 4WD

[bald eagle]

I am seriously considering getting myself a 4wd electric buggy. I just cant make my mind up on the best to suit me, so I am after some advice really.... Which is the best package? xx4.. spares availability is great, but is it too long in the tooth now? xxx4 i have heard is weak and breaks easily, predator, still has drivetrain problems so I'm informed, zx5.... spares availability????... I have a B4, so I know some parts would interchange onto a bj4...... any advice on this matter is gratefully welcomed...
