A decent rivetter would cost 50-60 quid, although the Afam one is cheaper and a good choice as it is just a rivetter whereas most sets include tools to assist the breaking of the chain, which an angle grinder will do. The link that was posted showing hollow and solid links need different tools to flare the link. Solid links are rarely chosen where a Whale is the best tool, as this is a hammered on link commonly used in race paddocks. There is a chain/sprocket kit using Ognibene sprockets which have the "silent" dampers on them. I deliberated over what to get quite recently, and eventually plumbed for a stock Yamaha front, which are quite expensive, and a steel Afam rear which is available in black, which I thought, looked good.
