Thought I'd post an update...
I bought a Ricochet Apache LED loader the other day for a couple reasons. As I stated above, the Reloader B is a little heavy. Plus, I was seeing a lot of double feeds with the Reloader B - likely because it's a force feed loader.
The Apache is about the same height as the Reloader B, but it's a heck of a lot lighter. There's a little 'bend' sensor in the feedneck, so whenever paint moves past, it bends and the contacts start the motor.
I like the Apache a lot - it looks better than the Reloader B, it's lighter, it feeds faster than I'll need, I didn't have to sand it to fit my Blazer (although I did drill the neck for the feedneck screws), and the simple one-button design makes it a snap to turn on and off.
The Reloader B was promptly put on ebay and sold.
Another thing... I haven't shot a lot of paint through it, but I'll expect to see less chops (due to my short stroking). With the Reloader B, the tension on the ball stack would have pushed a ball part way into the chamber as the bolt started to move back, and chopped the ball if the bolt didn't go all the way. With the Apache, since there's no 'extra' force on the ball stack, hopefully I won't have that problem. I haven't so far...
