I've never been one to purchase something sight unseen,.. I might have a few regrets on that policy but I expect less than actually purchasing stuff based on a drawing. Example is the Southern E8 set, didn't pre-order and everywhere says it's sold out, not available, nope, no chance. Which is ok, might find one later at a show or shop,.. which I can look at, hold, test run, etc,... Yesterday I stopped at a hobby shop and whoa,... there it was,..
And that other part, I've been running at a statistical 20% defect rate on new Lionel locomotives,.. The online dealers have made good, immediate replacements so all is good.
