What is the machine you reccomend to grind nuts into butters? Such as Almond Butter?

The Champion juicer makes the best "nut" butters since it tends to cause some friction when grinding. The "butter" will not turn out like store purchased "almond butter", since commercial manufacturers use high powered machines, and we have yet found any on a consumer level. Raw nuts tend to have little oil, which complicates the matter. Roasted nuts tend to have more oil, and will produce a better butter.
