I can understand your frustration. I went through the same process a while back. There have been so many Rolleiflex models, and it's really hard to find the "right" one. Eventually, I went for a Minolta Autocord, at a very low price and in good condition. I had it overhauled and had a Maxwell screen installed. I simply could not be happier. The focusing is very easy and very accurate. The controls are easy to operate. The lens is more than sharp enough for me. The camera is light and small. It even has a flash shoe on the side and a built-in meter. Finally, the cost of Autocord CLA and repair is much lower than that of a Rolleiflex.
I hope this post helps you instead of complicating things. If you really want a Rolleiflex, I second the opinion that you should go for one in as good a condition as you can afford, and factor in the cost of a CLA and a bright focusing screen. You may be able to do all of those for just under $1000, but be prepared to pay more
