chip help

[TeamLupin]

yo, i know of a place that is trying to persuade me to get a neo 2.5, but i am unsure if i want that chip. I live in the U.S. The recent nova chip sounds good cuz it can play imports. I so want to play The Keisatsukan(police 911), Resident Evil: Gun Survivor 2, wipeout fusion, onimusha 2 and tekken 4 and the place i mentioned has backups of these games(cdr and dvdr backups) and gets new ones every week. but i need to know what chip is best suited for my ps2? i bought my ps2 the first day it came out, oct 26, 2000(and no dre since) and is schp 30001. my serial starts off like this vU03*****, i think i have a version 2 board. what is the best chip you guys think? btw that place is offering to install neo 2.5 for $80 (i think is a rip)

thanx,
