But I'm not aware of any cheap pads that don't wear fast. With cheap pads, you're likely to run into a false economy. You'll either burn the pads fast, or the rotors, or both.
Do NOT commute on the street with race pads. Your pads and rotors will both wear EXTREMELY FAST. That said, you'll be fine swapping them in your garage the night before and event, and swapping back after you get home.
2500's are not race pads and are very common to run as daily driving pads.
Further, EBC yellows, while lacking the bite of more serious track pads, are widely hald to hold up just fine for someone just starting out. They are EASY on rotors, and have longevity comparable with other pads. They just lack bite at high temps.
Have you even used either of those pads before?
