How much does it cost to buy 1 Ethereum?

Could you please enlighten me on the current price of acquiring a single unit of Ethereum? I'm considering investing in this cryptocurrency, but I'm not entirely sure about the market value. Is there a standard price, or does it fluctuate frequently? Also, are there any additional fees or costs associated with the purchase? Could you provide me with a rough estimate or guide me to a reliable resource where I can find the latest pricing information? Thank you for your assistance in this matter.
