Amazon offers Prime members the Lionel Imagineering Non-Powered Train Set in four styles (Batman pictured) for $29.99 with free shipping. (Non-members can qualify for free shipping with orders of $35 or more; otherwise, shipping adds $7.48.) That's tied with our mention from a week ago and the lowest total price we could find by $9. (They go for around $50 or more elsewhere.) Each set includes two engines, two gondola cars, four curve track pieces, and six straight track pieces.
