Looks like the brake lathes are each dedicated to drum (the Annco) and disc (whatever the red one is). Red is usually Accuturn (FMC) which is a good machine and of course Annco speaks for itself. No sense in getting one machine. Get them both.
I cannot tell for certain, but I believe you are right. That is not a bad price if it comes with lots of the bells and cones, but if not a disc machine, then, no. I have an Ammco disc/ drum, but the disc carriage gearbox is screwed up, and you must hold the lever in while turning. While that is a PITA, at least it's workable. I had no idea, tho, when I bought it, that NObody seems interested in turning drums/ rotors any more
