This kit has been available for several years. We've (LHS) had the kit as part of our in-store common parts availability for our MTH customers. In fact, we've re-ordered certain groups of parts (e.g., traction tires, bulbs, et al) as needed.
It is a tremendous value for what is received, for sure. However, unless the individual is planning on getting into the repair biz, I'm not sure the typical hobbyist will find it worthwhile. Club purchase?.....maybe so.
Be interesting to hear of others' experience in this kit's purchase/usefulness.
And, yes.....we would be interested to see the orange/blue guys offer something similar for their vast product line.
