ISO "real" trike

[LISA STUART]

I'm an experienced cyclist but I've had surgery that has affected my balance (so I can walk but couldn't balance a bike continuously). I would like to get a "non-recumbent"/touring bike that just so happens to be a trike! Bob Jackson used to do custom orders. Roman Roads Cycles (also in England) appears to do so now. I've been measure by REI. Does anyone know of a US outlet that does this? Thanks!
