Hello. Are you interested in a D2100.1 as a straight trade for 1? I have done deals here with Audio_Phill and many others. On E-bay I go by felito79 and I'm at 100%. Don't worry I have 2 kids in school, I'm by the book type of guy. I just got a D3500.5 on 2 15" Havocs and I'm looking for a matching 2 or 4ch MMATS. LMK, I could be reached at 781-420-3215. Thanks...
