I would keep looking on eBay for new old stock unless you are in a hurry, much cheaper usually I have never paid more than a tenner for old stock ones. Veco bearings will most likely be from a reputable source it is more likely that bearings will be poor quality from unbranded listings. Old stock items will almost always be fag or skf in a suppliers box. The beta bearing is the same dimension as many renaults FAG list them
