Ken,
The reason I decided to make my own loader (+1 for a buddy) was because the new Triple-P units smell suspiciously like vaporware. It's not that complicated to make your own linked loaders, and MUCH less costly. All I had was a saw, a drill press and some time. Here's my version of a toggle link type loader. If I can make 'em, anyone can. PM me if your want a set of drawings.
