Hi there. My 14 year old son is interested in getting a train set. There is a lady on craigslist selling a brand new still in the wrapper Bachmann 137 piece "Rail Blazer" set for 50.00. Is this a good price for a brand new train? Is this a good "starter" train for him? I think we want something in the HO scale. Any other recommendations? Thanks for any and all comments and help.
