I bought mine for something like £250-$320, it was a fully built ready to troop kit, once I received it I decided it needed to go phew phew, something you will probably want yourself if your going for all the fancy electronic bits (it's kinda cool and the young lings love it) . Electronic kits are available from blast FX,
Jc27 amd even the hasbro fett blaster can be cannibalised.
My blaster came from a UK maker called
Sidewinder who also retro fitted the electronics. However there are us suppliers such as
jbdubz or
Hellhounds who recently developed a rubber con freindly EE3. If you want a more realistic version hand schab does I bronze cast version from what I remember.
