Hello need advice

I’m finally in a position to where I can start saving money and things. I only have 1k saved at the moment and want to start buying bitcoin in hopes I didn’t jump on too late. What would be the best way to buy? Like should I buy $250 worth or just a set amount every paycheck? Is there a way to get around a fee Everytime I buy some or is that just the reality of it? I open to all advice on how to go about this. Thank you guys
