Limit this feature and you'd be playing an entirely different game.
And like i said previously -- just keep those techs and simply, do not trade any IF that's what your feeling is.
True, but I confess that I do not have the self-restraint.

BTW with tech brokering and thus tech trading on, my usual set-up worked like this
Mil-35
Soc-50 (soc spills into Mil when nothing is built anyway)
Tech-15
Since I could easily get wahtever tech I wanted from others, I never concentrated too much on tech. Untill of course the late game where Soc and Mil were not as vital during stretches and I would max research.
I must be misunderstanding this whole issue. I believe no tech-brokering means that you can not trade techs you got from other civs? If that is the case, then how does a human player gain an advantage through this? (No sarcasm, honest question) Since atleast for me, and I kid you not, roughly 65-70 percent of the techs I have (when tech-trade on) are from other civs. Again, untill the late game. If this is not the definition, then my posts should be disregarded.
With tech-trade off, 0% of the techs I have are from other civs. If tech-brokering was not allowed, (as AN OPTION ONLY so as not to enrage others) a middle-ground would be found, no?
I know now that I play with no-tech trading, everyone has extremely unique tech levels.

Research is so much harder for me to keep up with that I really do think HARD about every tech that I research. I currently have maxed out my Beam Techs, but seriously have not even researched Mass OR Missle Theory.

I do have good defenses for both however since several other races have specialized in those.

My shields are very weak, but the two races using beams are far from me. With this setup I have never dropped research spending to below 40%; except in very rare occurences for a max of 2 turns or so. In fact, Research for me is genrerally over 50%
Finally, it is difficult to determine the mood/attitude one uses to post on the internet so FTR I am not upset, frustrated or even in the slightest displeased with the current set-up and hopefully my posts reflect that. I just find this discussion very interesting! --but not implementing a "no-brokering option" would not stop me from paying
double what I've paid in the past for the next chapter in this amazing game.
