I just got this at costco a few weeks ago for $30. I haven't done any slow cooking because it was mainly just a rice cooker, but it seems to have a good range of options. So far rice cooking and steaming vegetables works great. I'm looking into doing some slow cooking with it as well. This isn't the exact one but for $30 its pretty good. Check Costco if you can shop there because I think the options on the store one are better.
If you're on a budget I've been using this one for a while now. Kind of small compared to some of the other one's I've seen but the versatility is great. Does a good job at making rice and the programmable features make it super convenient. One of the major downfalls I've noticed, though, is that there is no high/low setting, it just "slow cook"s.
I have this one that does rice, steam, and slow cooking! I love it, it cooks rice perfectly and slow cooks everything. Only bummer is that is really doesn't have any settings or temp gauges for slow cooking. I had to figure out on my own that it cooks on low, and always make sure to temperature check my meats to make sure they are up to temp. Other than that, it's really handy if you don't have a lot of space. Not quite sure how steamed foods will come out, as I haven't gotten around to it yet.
