I buy soynut butter in the natural foods section of my grocery store, but if yours doesn't carry it you might need to go to a health food store. It tastes a lot like PB to me, but maybe that's just because I've gotten so used to it. If you've ever had soynuts, it tastes like them.... but creamier!
I buy I.M. Healthy brand. I use the regular creamy most of the time, but also love their chocolate once and a while as a special treat. Unfortunately it's a lot higher in fat, so I use that sparingly... but their regular is a lot lower in fat than PB!
