Im just a bit confused by what your actually wanting.
you said you want a mount that can track (im guessing normal sidierial etc)
Then you say you don't want to use a tracking camera?
Then you say you want to track and guide.
Unless your going to be sitting at the eye piece tracking then you will need a camera to stick in the back of the guide scope or on a Off Axis Guider OAG

the camera that is not on the axis of the main telescope is the guiding camera and the main camera is behind the big disk (thats the filter wheel). It looks complicated but it really isn't
for a start the HEQ5 or the NEQ6 are brilliant starters if your on a budget. If you think that you may be getting into astrophotography alot more scrimp and save till you can afford the NEQ6 as it will last you longer and hold alot more weight and inveriably give you options and flexibility in the longer term.
The HEQ5 i would rate upto a 8" newt with all the fruit for AP
The NEQ6 i would rate upto a 10" newt without too much experience required to handle it. and upto a 14"-16" CF tube newt if you know what your doing... eg adjustments and tuning of the mount guiding and the like.
The main thing that lets them down with the bigger loads isn't the actual mechanical parts but the motors as they don't have the torque to hold onto the load.
