I'm not sure if i have seen the price for the v6 being lesser than this. The v6 is better than the "core" in many ways - the most noticeable being the wifi connectivity and the all important auto calibration (does not require a spin up/down like the core to calibrate).
The same is available in bikebug too.
If a 99bikes shop is close to you - have a check on availability and save the $60 on delivery (and hopefully they help with fixing the cassette as well).
i expect the jetblack victory to squeeze these prices once it becomes more widely available
