Those were indeed the days and I miss them dearly.
I remember all of the models, fanzines and conventions. Making Tribbles out of fake fur and uniform tunics out of sweatshirts. I still kick myself to this day for not shelling out $100.00 back in the 70's to buy a Phaser off of Bill Hickey.
That being said I am glad that we have the days we have. All of the old models are available along with the 1:350 Enterprise which can be totaly tricked out. Tribbles are abundant for sale on the net are they come with sound and motion. You can also buy nice Phasers, Communicators and Tricorders all with lights and sound for a reasonable price as back in the day they were very expensive. Quality uniforms, props and blue ray remastered versions of the show are available.
So....in many ways these are the days.
