No - Ezi chips are VERY dodgy. They aren't at all easy to fit due to the rediculous tolerances on the chip clips (a fraction out, and you'll snap the legs off the mobo chips rendering your PS2 permanently useless).
Nothing better than a good, soldered mod. Go for the Infinity Chip and get somebody to solder it if you don't feel comfortable doing so...
I know people who could help you out, so if you are interested, drop us a Private Message...
