Source for RAM-LINE 10/22 Auto-Loaders?

[Rattletrap]

Anybody know where I can purchase some RAM-LINE 10/22 Auto-Loaders? (RAM 43001) These are the plastic tower loaders for Ram-Line's 10/22 banana mags. They used to be everywhere, but they seem to have dried up lately.

Any info would be greatly appreciated.

Thanks,
