Welcome to ASC,
This is the charger I have been using the past two seasons;

No complaints, very reliable and is simple to operate.
Thanks for respecting the age verification process, once you have access to the classifieds you will be able to see the vast availability wrt gear and AEGs.
You seem to have alot of questions, perhaps try hitting up a local game that is taking place soon? Check out the Ontario games section. Players love to show off their guns/gear and don't mind answering questions; you will learn more in a hour of "face time" than in a month of surfing the forums.
cheers
