I do not do any all grain, I'm still just at the kit stage; but I am looking into moving up. A conical fermenter would work with my kit beers as well, they just look great for removing sediment and easy bottling/kegging.

I'm not sure though if I should save up for an integrated system like The grainfather or just buy a couple of big pots and use those. I saw some diy versions on some homebrewing forums so I might try my hand at building one. Those big pots aren't cheap though, are they? heh.
I agree with the kit comment; the taste is similar, that's why I tend to use the same wheat beer kit as it works great as a base, lightly flavoured, clean and I can just push it to any direction I want.

Your set up is a few levels above me and I hope I'll get there at some point. Do you use cornelius kegs or something else? I've got a plastic keg, but never used it, I should though, maybe for the this batch as I'm low on bottles as it is.
You should do a post on your DIY system, or could you give me more details on how you made it?

Thanks
