What size of telescope do you want to put on it, and how portable does it have to be?
Don't underestimate the weight of the mount itself and how long it takes you to set up. That will make a huge difference how often you will actually use the mount.
Will you have to travel to a dark site, or will you take images from your backyard?
Having started with astrophotography about 3 years ago, I can tell you what factors have become important for me:
1) Fast setup so I can image at a moment's notice and don't need half an hour to prepare even in my backyard. If you always have to break down your rig every morning, schlepping it out again in the evening gets old very quickly. If you can let it sit there set up for a week, that is less of a factor.
2) Do you have to travel to a dark site? If you have to drive a long distance just for imaging for single night, you will not be doing that for very long, unless you are retired.
3) How much can you lift on a benchpress? These mounts can be heavy, so bear that in mind.
If you are just starting out, and if I were to do it all over again, I would be getting a very light travel mount that can carry a WO Z61 or Z71 FIRST. The iOptron SmartEQPro+ fits that bill. It can be driven by rechargeable batteries in the mount itself. It is full GoTo, but it is lower end, so not very precise on its own. To get good astroimages, you have to guide. But it weighs little, so I have my telescope with Pi4, camera, power supplies, everything set up on the mount itself and I just carry it out from my living room when I feel like imaging. Setup time is 2 min. I use that A LOT, simply because it is so easy.
I would honestly go that route. For $1K, you would get the mount, the telescope and the Pi4, basically everything you need to start imaging. Find out if you like it, gain experience, then upgrade to a larger mount and telescope next year. There is no upper end to how powerful you can go. But I suggest to start out small.
Hope this helps,
Jo
