Osgeld,
I have designed a family of serial LCD panels and backpacks with ATMEGA328P. I'm flashing them with my code and selling them in kits. My first 25 ATMEGA328P lasted 3 months, next 25 lasted 3 months. Not to use linear regression but just common sense, this 100 will last 8 months or less, the end of summer.
I wouldn't mind a catalog though. I find catalogs very useful in getting a feeling of what each part looks like. I can also take notes on the catalog. One is enough.
