Logitech USB Mic recommendations?

So, I was browsing through Best Buy the other day and spotted a Logitech USB mic sitting there with a price tag of $67.
Has anyone actually messed around with these things? I’m trying to figure out if they’re legit—like, what’s the actual audio quality? Is the floor noise going to be driving me crazy, and why on earth are they priced so much higher than those basic $10 junkers you find at a drugstore,$6.75.

My main goal is recording acoustic/classical guitar directly into my PC.

Generally speaking, the higher the price tag, the better the microphone quality.

That’s just how it usually works, I suppose...
