Yes CTD is pretty bad - famous for playing the game of setting the highest price the market will bear - they also used to be a real rip off on shipping - I haven't bought anything from them since the 1990s' when they had some deal on 1911 magazines, I think I ordered 3 and 2 were bad out of the box.
I put my email address in all the other websites to be notified when they will be back in stock, I am sure some will show up again eventually.
I will continue to look on ebay and gunbroker as well.
Thanks,
