contemplating to buy or not, is it v7?

[Demondus]

i got a v12, no hdd support so thats a bummer. been looking around for old model os ps2 and came across 3 used scph39001, i think thats the v7 correct? i have a hdd from my previous ps2 that went kaputz, so i'm contemplating whether to buy the used one if its really a v7 since they are supposed to be the best version of ps2. And since its used i don't want to put too much strain on the laser lens, so i'm thinking of getting a mod chipthat allow booting from the mem card itself. Need advice on ehether an MI or CC is best for v7? Thanks in advance for any reply.
