Anyone tried using a sous vide for bone broth?
The majority of slow cookers out there really suck. As far as broth goes, most of them are too hot so that you can't use the "simmer for 48 hours" approach to broth making. I have one of the few units with a "simmer" setting, but I'm constantly annoyed by it's smaller-than-desirable size (3.5 quarts).
A sous vide, though expensive, seems like a possible answer since the temperature can be set precisely. For broth, one wouldn't use a vacuum bag -- you'd just throw the bones in with water like a slow cooker.
The Sous Vide Supreme folks say it'll work. But I'm curious if anyone has actually tried it?

I've not tried it, but this article from the French Culinary Institute has me convinced that pressure cooking broth (with the right pressure cooker, see article) is the way to go!

Hm, I've never tried it, but I got a pretty good slow cooker (not to pricey either) that has a "warm" setting for serving. I think most slow cookers have it, I just put all my bones etc in the slow cooker, set it to warm, and come back about 40 hours later. The warm setting also isn't timed for most slow cookers, because it is a serving setting, so you don't have to reset the time like you do when you put it on "low". Because I took loads of microbiology, I can tell you that it keeps it just above the temperature where bacterial growth could be dangerous, so that's good!
I have cooked meat with sous vide at a restaurant before, it is a pretty good time, so you would have lots of other fun uses for a sous vide! Seriously, so much fun, we would put all kinds of things in the vacuum bags to see what would happen. They are very pricy though...I would personally look for a good slow cooker before springing for a sous vide, unless you plan and using it for many different things...

Swooping back in to (in a sense) answer my own question.
I emailed some slow cooker manufacturers and asked what temperatures they use at various settings. One manufacturer had a viable option: Hamilton Beach claimed that their Low setting is 190 degrees, which I consider to be right on the upper edge of acceptability for long broth simmers.
So I bought their 5-qt unit (Only $20, which I find amazing: http://www.walmart.com/ip/Hamilton-Beach-5-Quart-Oval-Slow-Cooker-Black/15126416) and gave it a shot. The Low setting ended up bring upwards of 210 degrees. But, the Keep Warm setting is 190. So I'm in business. :-)
