Cashmere is my newest addiction. I'm a little late to the game. I have been aware that it is regarded as essential, but I never really felt the urgency of shelling out $100+ for a sweater. Now I'm a believer for one sole reason: temperature control. It's amazing in making you feel warm yet not overheated. Brilliant for the extreme interior/exterior temperature changes during the fall and winter in a place like New York.
UNIQLO's cashmere sweaters are currently 20% off, which make them attainable for just under $70. Not the highest quality you can get but great for cashmere novices. Plus they've got any color you can dream of.
