For your car, an EJ25 swap with reground cams is really the best for your money...but given that you're asking about eBay chips, I'm guessing engine swaps are a bit beyond you. I don't mean to offend you, but it's what it is.
I have a 98 impreza L 2.2 sedan that has some newly rebuilt heads and the delta 230 grind cams which is really similar to the delta 2000's for the ej25 NA motors and the car definitely has some more power and get up and go starting at 3k rpms up to 6k which would go to 7k if it wasn't for the fuel cutoff.

Cams on these motors with a better header, one high flow cat and a none restrictive exhaust yields some gains.
