I'm finally going to invest in a motor, but I don't really need/want a disecq H-H system so I found this one, it is not built for satellites but would it be usable?

Not a big expert on these Leonard, but it looks like it only moves in the horizontal plane and will not be suitable for the semi eliptical path the satellite dish needs to follow.

Yes, you are right it is only horizontal movement, but how many degrees vertical is the difference between South and 75 degrees to the west/east from south?

Its quite a few Leonard, if you get the Swedish microwave calculator and type in your location, then the extreme ranges of the required satellites, you will find that the elevations can be 10 degrees difference on the extremes of a small arc.

ok, that was quite a difference, sometimes up to 15 degrees, so do you have any recomendations for me? I would like to have manual or a special box for the alignment of the dish.

A little less analogue, and a lot more crap.

Depends on your dish type and size

If a large size or prime focus antenna it might be useful to buy a polarmount off the shelf and bolt it to the back.

If offset with a pole clamp arrangement then a complete motor/gearbox would be more economical

i have a rather small dish, 1.00m, so I figured out that a Disecq motor with a disecq steering box would be fine for me.
