The Front hubs are actually Q/R which. According to Scott from Level his is because of their original intent to make these hubs for MTB's who tend to use quick releases more than track bolts.
We have talk in length about this (and my unhappiness with no track bolts) and I believe that eventually they will sell them with an allen key Q/R in the same design as the rear bolts, but until then...Q/R it is...or krypto locking skewers.
For prices, check out the bikeophile site linked in my sig. Black is the same price as silver currently (unless level decides to change the price...no plans to do that as of yet anyways)
