Found a product called gear floss and I'm absolutely hooked. Hard to beat for cleaning brackets and cassettes, and reasonably affordable. Anyone else using it or something similar?

Other than that I've found kasai lights to be a pretty nice, entry level lights that don't use a proprietary elastic band that'll break in a year. Also pretty cost effective as I recall. I'll also second the blackbibs.com comment as their stuff is both quality and cost effective.
