Just ran across this annealer.  I'm always a year or two behind on new gadgets.

From what I read the cartridge feeder is an accessary. That would be a good question to ask the maker of the annealer.  It's pretty expensive.

Whoa. That's a pile of money.  I just happen to run across the link I posted.  Thought it was pretty neat.  Have to do a lot of annealing to justify that kind of price.   

I agree with you.

Speaking ‘bout annealer, I first tried the stand-the-case-in-water-and- apply-a-propane torch method, which did not work well. 

Next, I tried a case holding collet from a Lee case trimmer, but it took too much time putting on and removing a case. 

Now I use a ring burner from the Woodchuck Den. Place a torch holding the burner in a vise, hold the cases in the burner with old kitchen tongs, and when annealed, drop  in a bucket of water.

Bought it several years ago for about US$45 - 50.00.

I spoke with the folks at Giraud about using their annealer on rimmed cases and was told that as they supply it, it won't work.  Apparently, that also applies to belted cases and any case with a tapered body as well as they do not sit well in the hopper.  I use a Benchsource annealer I got from Buffalo Arms. 
Given the price of the induction units, I can continue to use my propane torch annealer for approximately 95X my remaining life expectancy before breaking even, even if electricity was free.  Of course, not having one means I'll never be one of the cool kids.
