While the great wisdom of Sheldon must be respected lest the universe tilt off kilter, I still vote that a list of track bike manufacturers would be at least marginally useful, or at least a list of quality builders as voted on by the bike forums populace. of course there could be divisions for entry-level, mid-range etc... perhaps a new thread. and yes by all means a list simply of bikes with track dropouts is useless. But a list of true track bikes and possibly even the best horizontal dropouts--which are safer, would be a nice "search for thread moron" landmark---seeing as there are debates in nearly every "I'm building a fixed gear thread"... as to what is the better frame/the same frame, etc.
