my friend got one for around 2000 Rs last year ...if i remember correctly ... i told him about this HDLoader workaround to be able to save loads of games on the HDD inside his ps2 ..he liked the idea ..we did a little search ...and then everything went well ...the network adapter isn't tough to find at all .. atleast not Imperial Market, Rawalpindi.
Also, the person we bought and paid to install the HDD for us works at Lahore Electronics, Committee Chowk, Rawalpindi ..he's a real pirate ... loves to rip you off .... so beware if you wanna give him a chance 'to help you out' but he's got quite some accessories.
wats strange is this fact that, that moron would chareg 100/150 rs for a ps2 image to copy it to ur hdd .... what we did was just analyse all that 'procedure' he did to copy the games to the hdd ..and then ... we paid him for the first and last time .. now all his games are managed by him .. he's got like 12-15 games on his ps2 on average which is pretty nice ..
