Where to buy seperate parts?

Looking for Flash wheel, and for anyone asking the same question I'll put any links in replies here
eBay is a good spot, watch out for cheap ones, as they are usually fake. Whether or not you'll find a Flash wheel is a mystery, as it's mostly tips and spin tracks, but you might find a wheel somewhere.
I give a good tip instead of buying the parts you can get the rapidity or fake beyblade and u can usually change the parts.
EBay is good place to buy separate parts
