I'm wanting to extend the growing season here in KS and put in a decent greenhouse. We've had a HF special for the better part of a decade and it served its purpose for getting seeds started early but it has reached end of life. This time around I am thinking about going more upscale and long term. I haven't been thrilled with a lot of the prefab options I've looked at.

After a million rabbit holes I'm currently on the train of thought of buying a prefab Versatube frame only type structure and then covering most of the sides and the roof in Solexx or another multiwall poly greenhouse material. Is that overkill or are there better options out there?
