Why do these threads always have to turn into a flame war?
For bashing the MGT has plenty of steering. It does ok on the track too, but it's not as good as the LST trucks or Revos steering.
It's always nice to get a brand new truck, but if you can get a used one that is in good shape it'll save you money. I personally don't like to buy used unless I can look it over before buying it, but several people have got good deals off ebay.
