Wheres the link gone ned? You posted it up this morning and now its gone
Anyrode, had a look at your link and yes thems the ones.
Spoke to a Chinaman in China (yes, really) called Ivan (yes really I fookin know) about 18 months ago....he manufactured rads in an ultra modern manufacturing unit. Asked him about rads for Birds and he said yes no problem, send the drawings and for an order of no less than 200 he could sell me them for 12 dollars apiece! I declined the kind offer due to no drawings, cant be arsed, no money up front and no business acumen. Looks like someone has all the attributes hence the prices of the rads we see on ebay. At 45 and 70 quid compared to err, other places Id say that's worth a punt.
