I have to disagree about the importance of chainline on a fixed gear. A moderately bad chainline will cause noise and wear. A bad chainline will perhaps cause the chain to jump off the cog. No one who has had this happen on a fixed gear would call this fixy-babble.

Get the chainline right. It is not hard, and with luck is not expensive.
