Gentlemen,
Again this all depends on the amount of money you are spending for the used items, I would not purchase a used Legacy Shay if I could pick one up at Patrick's trains for just a little more money, the same goes for FasTrack Command Control switches, when Charlie N has them on sale each year, NIB for great prices. I better be getting one heck of a sweet deal, to purchase this kind of equipment used, when I can get the complete Warranty, this is especially true when purchasing a DCS or Legacy system. In fact I want the dealer warranty on both these items.
