There is also the Thompson Machine Zephyr for a 22. I've got one on order so I havn't used one yet, but I've read goods things. They are a little cheaper also.
Did you hear a live demo of this can? If you have, please let me know.
I had two of my customers want Thompson 9mm cans. So I ordered 3. They were cheap - $140 each.
One for each of them and one for stock. After testing all three, they were all about the same in quiting. The one I have left is not worth the paper that it was transfered on.
Cheaper done not equate to better. I now have a couple different cans that were inexpensive that I have to rack up to learning experence.
Good luck with your Zephyr
