You are over-thinking this. They are all fine...Formula, Dimension, Surly, IRO, Soma, Ben's, Harris, etc. etc. Just buy one thats spaced to 130 or with an axle long enough to space it out to 130. All these hubs are equivalent quality, non-bling, perfectly functional hubs. A fixed-fixed flip flop gives you the most options, because you can run fg cogs or freewheels on either side.
