Not alot of options for fixed.. the axle replacement and spacers you would have to play with spacers to get the correct chain line. SInce a standard fixed up cog spacing is a bit different thena mountain bike single speed spacing. THe surly adapter is expensive, so might as well spend few extra dollars and get a phil which will last a lifetime.. I've heard good things about the van dessel hubs though, and they are not expensive at all.
