Careful ! The only Dorcy's I see on Ebay right now are the Dorcy Metal Gear type - and that is not what you are looking for, is it ? You are looking for the CR123 powered Dorcy "junior" correct ?
If anyone needs these lights, they are $20 plus tax at my local Target store...IF you have bought a diode from me, and wish me to include this in the package - you can pay the retail price, plus the extra cost of shipping. If you want it sent via priority mail - that is close to $25.00 by itself, so that would defeat the "inexpensive" part of the hobby, I believe ! PM me if you need one sent with your diode(s).
