cdnn is out of stock on their web page.
--I have never purchased from them, but have herd good things about them.
Midway has a limit of only 2 per type of magazine, but if you buy more then 1 unit, they wave the special handling fee and just charge you a fair shipping price.
--I have purchased from them before, and liked the experience and quickness of shipping.
eastex has them for 22.44 and a flat shipping of 9.99. This is the best deal if you are buying more then 2qty of a magazine, there seems to be no limit on quanty, Shipping is the highest of the three but its a flat shipping on total order.
