Just bought a complete Mini-E/BMS/coil kit from Vector - ended up just going with the coil/PSU combo since that was the only option.
Waiting to confirm the specs on the PSU as the initial 48v 35A one offered didn't fit in the package for shipping.
Pretty good communication with Vector, and the response is quite consistent (much better than Luna so far).
Will make a post on my build and how the controller performs (pairing it with a MXUS 3kW Turbo).
Heard good things from my friend with a Mid-E and Mini-E, but another one with a Max-E has had some issues (his own fault mostly). Excited to get my kit running!
