I think I understand what you are asking, but I am not 100% sure. Yes, the 1A Raingutter Tower like you show in the picture fits the 80 series and most other vehicles with actual raingutters. A few cars need the "high rise" extender blocks to make the tower taller to clear a bubble top or something like that, but on an 80 Series, those aren't needed.
A quick search on eBay shows that there are lots of used ones available. They are pretty tough, but the one thing that can happen is that the hand wheel to tighten the tower to the gutter can get stripped out so be aware of that when buying used. They can also accept a lock cylinder and many of the sets on eBay have them. The keys are all still available from Yakima along with the lock cylinders(they are numbered on the back side of the lock cylinder).
There is no real consensus between Yakima and Thule, at least for this application. Square bar vs. round bar but really, they are about the same in terms of quality. Most Yakima accessories like bike racks, kayak cradles, etc. will fit on either Yakima or Thule.
I have had both but I have had several sets of the Yakima towers over the years and I have never had a problem with them.
