I haven't stopped. I just got a Tech3 with stylus and was happy, until I read the instructions and found out the Tech4 had a .7mm pencil instead of the Tech3's .5mm. Soooooooooooo the Tech4 in chrome is the latest.
I have a boatload. I love my desk sets and perhaps one of my favorites is my Mark Cross leather desk set.
I must agree with most people that quality has diminished since leaving the US, but I still love them. I have a couple from Ireland that may even surpass my US pens and pencils.
My all time favorite has to be the classic century 10k pen and pencil set with the old .9mm pencil. It just says affordable class to me.
Here's a few.

I also remember as a kid, finding a four color pencil of my dad's. He got it in Germany while in the service. A few years ago, on another forum, I saw a similar pencil. One thing lead to another and.............................
Here is my collection of Norma pencils.
