I'm the first to agree that Wacom tablets are probably overpriced and there are now many really good alternatives to Wacom that people should look into before purchasing. I'm just commenting on my own experiences. My Cintiq cable is still fine after more than 5 years of use (along with the rest of the device). And at different times I've had similar pen sensitivity problems across four tablets from three different brands. In all cases it turned out to be due to driver conflicts that I had to resolve without useful advice from the manufacturer - and although I'd certainly describe Wacom support as unhelpful it literally wasn't the worst.
