Moog Slim Phatty is an amazing deal in the used marked right now. Much more musical than a Micro/Minibrute, more versatile than a Minitaur (not just limited to bass scale) or a Vermona Lancet. Definitely sounds more personal and less sterile than a BS2. For me the tone is even better than the Sub Phatty in a smaller footprint. Only downside is the long warm-up time but you can learn to live with that.
