[Buying]  Newbie hunting parts

Hey all! I'm new here and go by Ace. I'm on the lookout for new pieces to an old collection of gen 1 beys. I've got some interesting beyblades already but I need some parts to complete some of my current WIP stuff. Namely I'm looking for an original Bakushin-oh bit chip (preferably with the snail bit beast) as well as a 10 Heavy weight disk and perhaps some recommendations for good defense bases and zombie parts. Any help for a relative beginner would be very nice!
