Any advice on where to get a decent quality high flow alloy radiator for my bugeye?

I found 53mm alloy rads on ebay but they are sent from China and the TIG quality is pretty crap on the ones I've seen.

Japspeed seem to sell a 43mm core but with their name painted on the core which I rather not have.

Any pointers would be gratefully appreciated.

Thanks

The oem radiators arent too bad. Seen many cheap alloy ones fail. The oem ones can cope with high power
