It starts really with the sensor size you want to image with. Full frame or "medium format" as in the 16803 CCD requires a huge amount of optical and mechanical perfection.
But these days there are a large number of excellent sensors from smaller than 4/3rds to 4/3rds to APSc. APSc is often considered a large sensor these days.
The ASI/QHY183, 294, 1600 sensors are not demanding or require large illuminated circles so work from which sensor you are planning to use and take it from there. Factor in if you feel you are likely going to want to upgrade to larger sensors later though as filters, filter wheels etc need to be larger also with larger sensors. Everything is more costly with the larger sensors.
I have seen plenty of stunning images from these smaller sensors though so don't think you would be slumming it using one. Not at all.
