i would guess at neo2.2
how much did ps2 with chip and ar cost
were u get it from
ps2 no games £200
ar is £30(guessing)
£230 fitted neo2.2 about £20-30

I bought at USD408 in Malaysia with:
Chipped PAL PS2(30004) + AR2 v1.92 + 2 Analog Controllers (1 original & 1 third party) + 1 DEMO disk + 10 CD Games + 5 DVD Games.
