B> Sundown Audio SAZ1500D or Lower models

Product I'm looking for:
Sundown SAX-1200D
Sundown SAE-1000Dv2
Sundown SAZ-1500Dv2

I'm needing atleast 600rms x2 (I'm going to be running two E8v3 *which is 300rms a piece) I only want Sundown amps...no other.

I also need a SAX-100.4 (A,B,C Revision) for my interior speakers.

Budget:

Under $300 per amp (mono and 4 channel)

Condition:

10/10 functional
9/10 cosmetic (I don't have a problem with scratches by the screw holes. But I do not want amps with scratches on the faceplate)

the sax 100.4 is discontinued ,replaced with the 125.4 ,and if your interested in new they are both over your budget tho
