How much does it cost to buy Sol?

Excuse me, could you kindly elaborate on the current cost to acquire Solana, or colloquially known as Sol? I'm particularly interested in understanding the financial implications and the market trends surrounding this cryptocurrency. Additionally, are there any fluctuations in its price that I should be aware of before making a purchase decision? It would be immensely helpful if you could provide a concise yet comprehensive overview of the expenses associated with owning Sol.
