The GST comes with the starter pack. It did when I 'Had' mine. Listen to what chris says. Get Gloves! Your hands will thank you. The primer pump is a good upgrade as well as a 5 cell reciver pack. The AA batteries are not very good, dont provide enough voltage, so a 5 cell reciver pack is a good upgrade.

And Im sorry that no one helped you for awhile. The CEN section does not get looked at that much anymore. IMO CEN is losing their customers.
