My Budget Considerations
I always balance features with price. Basic models may work fine for simple tasks, but I’m willing to spend more if I need better sensitivity, stronger filtering, or more advanced reporting. For me, the best value is not always the cheapest option—it’s the one that gives me dependable performance for the money.
