I am planning a G scale loop around our new baby's nursery. On a limited budget I am planning on buying a starter set and of course extra track. Can you guys give me some opinions on quality of the starter sets? I have looked at Bachman, LGB, and Aristocraft. I have been told the Bachman sets won't last as long as the LGB. But the LGB cars look a little cheap to me (plastic wheels). I've only seen the Aristo pictures but they look decent. Also the Bachman track is aluminum? It looks to me the Aristo and LGB are solid brass. The track will go around the room on a shelf, out of little fingers reach. I want it to last many years, so I would like the best quality/quietest of the starter sets! Which sets should I look at? Also any tips you can give for wiring, track laying, etc would be appreciated!.
