I finally got my GG ordered but I didn't order the one with the batteries because I already have a lot of batteries. I didn't even think about the spacer until I saw a video. It is very hard for me to get to see a video because I am on dial-up. I have the CR2 batteries so I will be able to use it without the spacer but I might want to try the 3.7AA batteries. Can I get the spacer in the USA? What would I ask for? Also I know I will need to get the sand paper. Is there anything else I will need?
