Purchase Consultation (MFB + Burst)

On amazon, most of the gt beys are fakes even though the seller says Takara Tomy. Do you know of any reliable sources for the new gt beys?
Is wizard Fafnir a good addition? I'm wondering if I should buy ace dragon or wizard Fafnir.
looking to get into this game as a hobby, but i only have a few early burst beys that i cannot identify, 2 metal fight ones, and a cracked old hasbro stadium. i am hoping to find out what i should look at, as i would like to have at least a small collection of burst series beys (i just realized that this is not the right place for this, sorry)
