Any used gear is simply a chance if it's OK or not so there's that issue.
"Is it a good deal?" might be your question but I don't know your market.
sorry for bad English
Please advise me.
One person who I care about PC when something goes wrong, so I asked him to or not a NTB which has 4GB of RAM and 1GB graphics (he has in this area many contacts).
He gave me such an offer:
Toshiba Satellite C660-1P8, Core_i5(2410M)-2.3G 15,6"HD(LED) 4G 640G DVDRW WL(n) nVidia(315M/1G) CAM BT W7HP 64 bit
and letters that the NTB has been exposed in some store and that's a good price 250 €. This man is a true connoisseur, there is no problem with the PC, which would sometimes I could not fix and I consider it also as a credible, yet I want to know and independent views. I'm with laptops do not have much experience.
