I know I'm going to start off another controversy, but I still feel a small keyboard amp Roland, Peavey, Behringer, Crate, etc.) with an XLR mic channel would be a simpler, better solution to the Logitechs. A musical amp is better designed for the input/output signals of keys and mics. Otherwise a mixer is needed (more equipment). Also, $100-150 for a Sunday afternoon is to be expected.
