Lakland 44-02 (4-string) or 55-02 (5-string) has that configuration, with a tremendous variety of tones. They're outstanding basses, extremely well made, but pricey, though -- around $700-800, used, or a little over $1k new.
Here's a link to the 55-02 on the Lakland website:

MM/J configuration is not unusual. I'm sure others will chime in with recommendations of their own. Musicman Bongo is available in that configuration, as well as others.
P.S. I'm in Portland, too. I'm eagerly awaiting a Lakland Darryl Jones 5-string with a J-retro preamp. Should arrive in the next few weeks, and I'll post a review.
AppleMusicRow in Portland had a 55-02 a few months ago; I'm not sure if they still have one in stock, but you could call, and maybe get to play one in the store.
