Can't say where you can order one on Caribbean, but for New York you should visit Sew right.
Binding was my second reason for buying a coverstitch machine (my first one was from Brother too). I wanted a professional hand made look when I just started. My first several attempts to bind my test lycra strips were just laughably awful. But it is possible to bind with coverstitch and you won't need a second machine. It could be tricky, though.
