What 4WD to Buy??? Help Help

[riftan]

Not sure where to start......there are too many people saying different things.
I just sold my brand spanking new DF-03MS and DF-03. And still sad that I let my DF-03MS go.

Here I am looking for any advice from you guys. The car I am looking is for bashing only....full dirt and a lot of dust and gravel. Maybe down the road I will race it. It should follow the following criteria (the higher is the bigger the priority for me is):
1. Shaft driven
2. Durability and less problematic due to bad design, bad material and bad build quality. (oil leaks, breaks to easily etc)
3. Parts and chassis potential
4. and....brand new

Not sure if I should buy over engineered original Tamiya Avante or TRF502X. And is TRF502X OK for newbie?

Any recommendation for me please.......I am open to other brand
