If you want the MM-style sound, John East makes a 3-band MM style pre. It's available at Bestbassgear.com for $230 (or $207 if you sign up for the newsletter).
If you're looking for a good 3-band pre in general, I think there's a ton of options that get a lot of good reviews... Aguilar, Demeter, Nordy, Audere... the list goes on.
