I am not sure if anyone has mentioned the Skywatcher Az-GTi note there is also GTe (cut down version without encoders) can be modified for EQ use, I have seen long thread on CN where people have done this with good results as for long exposure work.
I was looking at this one locally here and have asked if you can get without tripod, but no response yet. This one is modified already for EQ use.
