How about the Brooks C17? This is their non-leather saddle, made of rubber covered with canvas, and is available with or without a cutout (I needed the cutout, you may or may not). It is fairly T-shaped; I had some slight inner thigh chafing with a Selle Anatomica and have had none with the C17. It is quite firm, so be aware that it may make your butt sore at first if you are used to a softer saddle.
