AB probably has about 2/3 of the US market with Siemens getting most of whats left. Modicon however gets a good chunk of the left over scraps. If I were to hazard a guess the top scrappers are Modicon, Omron, GE, Koyo. However in our area there is a serious lack of vendor support - a distributor exists but absolutely no one on the distributor's staff has a clue about the product, which means no one is pushing it in our area. We are mostly an AB house but we have twelve 984 racks. When we need Modicon stuff we go out of state rather than deal with the local boneheads.
