i don't know why people are offering so low for a working ps2! i was trying to sell mine too as it was useless after i bought an xbox. but decided to keep it instead. i might follow zain_khan1's idea, and gift it to someone! getting 2000 rps for it just aren't sufficient enough for the times i've enjoyed playing it!
Anyways, good luck for with the sale! And don't just give it away! wait for a proper offer. or just gift it to someone!
