Statjunk,
By 100 round drum, I'm assuming you're refering to the Beta C-Mag 100 rd dual drum. And yes, the price has significantly dropped on these, though you're waiting time will be a while (a month or two easily). To get the full package, (drum, speed loader, dust cover, graphite tube, manuel, and nylon case) you're talking $240 + shipping. To get the standard drum, graphite tube, and manuel, you're talking $200. As far as what nomercy, I don't know what he's talking about. Because every person I've talked to has had nothing but wonderful things to say about the Beta Mag's performance. They function flawlessly. In fact, they meet all military specifactions, and are used my many special forces in the US ARMY. I'm currently on the waiting list, and I suggest you get on it too. Because if John Kerry has his say, these things will never be available again. The cheapest sites I've found are as follows...
