I need to get an octatrack power supply, don’t really feel like spending $50 and waiting for an official one shipped from europe… looks like it takes 6v 3a dc. Any reason something like this wouldn’t work? http://www.ebay.com/itm/NEW-V-Infinity-Power-Supply-3A-211DN06-6v-3-3a-/321396073331?hash=item4ad4b2e373:g:fdgAAOxy9X5TZBuJ
