To convert a HG hub (splined freehub, the most common hub these days, in other words: the thang you gots) to single speed, you only need a $15 conversion kit, which you might even save, if you just get a PVC pipe of appropriate width and cut it to correct length. Keep the splined lockring from an old cassette, and get a Shimano BMX cog (by the way, anyone has an idea where I, living in Finland/Europe, could get one?).
In any case, to convert to singlespeed, that's all you need, no expensive SS hub necessary.
