I need to buy a new Standard Gauge Ives steam locomotive and have the option of buying a Proto-Sound 2.0 or a Proto-Sound 3.0 engine. I have no experience with Proto-Sound 3.0 and that version would cost me between $100-$200 more than the Proto-Sound 2 version. I am wondering if 3.0 is worth the extra $$$. Your thoughts and recommedations on 2.0 vs. 3.0 would be appreciated.
