The Dahon VISC D18 Tour comes to mind for your parameters and stated budget.
One size frame. @ 230#, you're at the upper rider weight for this bike (and most folders). That's kind of no big deal, but don't load it up with 50# of touring gear and ride it down staircases. Lacking a local dealer, thorusa.com is the national distributor for the USA if that's where you're at.
