I started selling on eBay in 1997, that account is now DGD_Surplus and is my full time business account. This account which uses my original user name is my personal account. I use it to sell my hobby and personal items in my spare time. I hope you find something you like. If you have a problem with something I have sold I hope you reach out to me prior to leaving feedback as it is my goal for my customers to be satisfied with their transaction. Dan Batson
