Awe, shucks. Thanks for the props foppa. I was just going to tell the noob to use the search or get lost, but now I guess I can't say that, can I?
j/k
Yeah, I don't really have much to add. Spend some time looking around here. There are guys with automated RIMS, HERMS, direct-fire, steam, you name it. Some are probably a little more difficult (and dangerous IMO) to DIY, so pick something you feel comfortable with and go with it. I use direct-fire + recirculation and it works well for me.
