The reason because I prefer good quality tools is very simple: once I have bought one of them, if correctly used it will continue to work flawlessly for several (even 15-20) years.
Please remember that I use my tools in a professional way (daily usage) and not once or twice a month.
If you prefer to use cheap tools, good for you. In the long term my 50$* will cost less than your cheap 10$ apiece which needs replacement after few months of usage.
I have some good mechanical tools (inherited from my father) which are old like me (50 years) but even for today standards they are flawlessly (their look can be a bit outdated...).
Maybe he spent lots of money, but it was a really good investment.

Sorry, but I'm not able to make the comparison,
lacking cheap cutters.
But please take a look to the photos I posted in the
tweezer thread: You'll discover the difference from a cheap tweezer (used only few times) and some good ones.
*) I do not know where you got the 100/300$ unit price: I warmly suggest you to change tools distributor!
To my knowledge, 40-60$ apiece is the right price for a GOOD general purpose cutter (in 1 quantity)
