Eastway is made by who it always was - probably a Taiwanese or Chinese.
The brand - which is all it ever was - is now owned by
Wiggle.
That's no criticism, many 'manufacturers' are, in effect, brands.
I'm no expert on cranks and bottom brackets, but Full Speed Ahead is a recognised brand, so I doubt there's much wrong with their products.
Bottom brackets are fairly cheap, so if the FSA one conks out, it could be replaced.
