Where is a good source (besides Ciener) for these mags?  Keuhl has them for same price as Ciener - was looking for maybe something cheaper.

Only break I know of (slight as it is) is get 3 at once from Ceiner (3 for $150 vs $ 55 each?) and sell off the leftovers depending on how many you want. At the same time order a couple spare fireing pins as they are the part everyone breaks somewhere down the line. Ceiner charges $10 to ship if its a whole box of stuff (good deal), or just one little tiny part. (sucky deal).
I have always felt the $50 to be kinda high but they are the only game in town and the mags are a good reliable design that can be popped apart to clean real easy. With a blowback rimfire unit blasting all kinds of crud down the mag this feature is tops in my book!
It could be worse,before the ban expired I smacked down $100 at a gunstore because it was the only one I had seen for sale in 3 years! At the time we still had about a year left in the ban and I wasn't shure what would happen and thought at the time if the feds didn't screw me that my stupid state would. As it is We in CT have about everything that was in the federal ban and more but we have gotten relief on magazine laws.

yep
