You know the guy that HAND-DETAILED all of his locos and rolling stock, and amazed everyone at the club?  YOU'RE THAT GUY.  Up for bidding is a HO DCC Sound/Lights Circuit Board?  I don't know what this is, but luckily YOU DO!!!  See my MANY other auctions for more overflow from my layout.  I will ALWAYS combine shipping on multiple items purchased, so wait for (or request) a combined invoice before paying.  The more you buy, the MORE YOU SAVE!  Enjoy the auctions, and Good Luck!
