I bought a full kit of motors and pre-built circuit board from Bartels a couple of years back and fitted them to a large Dob I then had - with a view to making it a Go-To and tracking Dob. Well, it worked OK even if the slew rate was a bit on the slow side but I found that it was too easy to make a mistake and too unforgiving of mistakes. I blew a circuit board that I had to replace and the chap who bought the scope from me also blew a circuit board in much the same way. It was essential to a Bartels setup that you plug all the cables in before applying power to the system. If you had a bad connection or forgot to plus a cable in to a motor and tried to do it after the device had been started, it seemd to eath out and cook the main IC.
So all in all, my experience with Bartels setup is a bit negative I guess. And in the end it cost a heap more than an Argo Navis.
