Yes probably. You will be better off with a good Adams unit. My favorite among the doorstop versions is the Jack Raymus version, with full rivet detail. It is difficult to assemble correctly without a good end mill, but it is gorgeous.
The better idea, if you do not mind plastic, is any of the currently available Lionel, MTH, or Williams versions. I have seen some of the work Lionel is doing, and it is superb. I just do not do plastic locomotives.
I really loved and respected Jan, but his kits were generally unsatisfactory.
Opinion.
