[Buying]  Looking to Get Old Takara Tomy Unopened Beys?

What's the best way to get TT versions for the following:

Flame Libra
Flame Saggitario
Dark Gasher
Thermal Pisces
Earth Virgo

And PreHWS:
Escolpio
Libra
L-Drago
Pegasus
Virgo

I looked online and they are insanely expensive. The cheap ones are fake. A Flame Libra was even going for 100 USD

Also I care alot more about the Metal Fusions so they are priority because I grew up with them and they are my "Good ol Days". (I wasn't aware of beyblades before Metal Fusion)
