That's what I use these days and a crockpot....my mixture temps will get up to about 260F if I use a larger amount (lately I've been whipping up 20ish grams of weed at a time) but when I cooked small amounts I found that you really have to watch carefully or the temps WILL climb too high.
I think the temps that work best for me are between 220-250F for about 3 hours.
