I bought this only a few weeks ago but having had the chance to use it at Astrofest I don't see that the difference with my dob is significant enough to need it for me. Perhaps the coma just bothers me less than some but it is also because it won't come to focus when used with my manual filter wheel and the latter is more important to me.
Price now reduced to $680
It is in as new condition.
