That item is a Magnum Dynalab MD102 that I bought direct from MD after I sent my MD 90 in for service. They took my unit in trade and I was into the 102 for cheap.
My amps were used but everything else was new and I paid less than I would have on line. My last few purchases were with Audio Visual Therapy in NH where theres no state sales tax. Great guys to deal with .When I bought my speakers they pulled out several amps, including a pair of amps that I owned along with setting up a sub with them. They spent time, were not pushy , and it was a fair price, not to mention saving $120 in tax . But most importantly they spent time with me so they earned my patronage and loyalty.
