I would buy the Heng Long PZ III with the metal track up grade. This will give you a fine running tank for you to get your feet wet. The Walker bulldog is very sound too, but doesn`t have the WWII history that many of us like. Get the smoke and sound electronics, they are much better, and if you keep it properely cooled are pretty robust. Once I figured out you need to flip them over to expose the cooling fin, I haven`t cooked a board since. I add heatrsinks as well to ensure the heat transfer rate is suffucient to keep the electonics cool.
