Oh ho, want old but valuable notebooks? You have to look hard yo

Try these:
15.6"
Lenovo
Z500, i5-3230M + Nvidia GT740M@RM2299[2.2kg], 4GB, 1TB, backlit, W8; 2 years warranty
Z500T, i5-3230M + Nvidia GT740M + (1366x768, touch)@RM2499[2.2kg], 4GB, 1TB, backlit, W8; 2 years warranty

Satellite L50-A100X/XW, i5-3230M + Nvidia GT740M@RM2199[Onkyo], 4GB, 750GB, W8SL; 3 years local warranty; colors:silver/white
These are relatively older notebooks, so they are harder to find, but the prices should be cheaper as well

upgrade to 8GB RAM at least
Recommending these because of the Mobile Processor, which is more powerful
