I was looking up the prices on the "Super Console X" and that's a hard pass from me. The controllers are throwaway value and you can beat the system itself for less than $30. I see they are selling between $80-$140 online and that's just crazy. Hard pass from me. It sounds like a lot of people selling them are using the included ROMs as the primary selling point which is something I definitely do not like encouraging. No one should be marketing the sale of ROMs.
