A slightly cheaper alternative. My Speedmaster was down for three whole days because I'd ordered a chain that was too short, and I couldn't stand not having the bike not running, so I went and bought a Parts Unlimited X-Ring chain. Yeah, it's the "generic" chain, but it was less than $90, and aside from the lack of plating on the side plates, is mechanically identical to the D.I.D. chains. I have to spend a little bit more time cleaning the chain, but that's no big deal to me. Point being, there are somewhat cheaper options.
