WTB Tandem

Mama bear like to ride but not alone. However, our speed differences are too far apart to allow us to comfortably ride together very often, so we're looking into a tandem. Figure if she's attached she won't get too far behind.

Looking for a smallish frame since I'm on a 55-54cm while she's a 52. Looking for something in good shape with decent componentry for less than $1000. Anyone knows of or hears of anything, let me know.
