I wouldn't recommend 2nd hand or reconditioned Laptops to anyone. If you are looking for to do menial stuff , Word, Excel, portable studio etc you don't have to buy top of the range. Last year I bought an HP G5000 to do the aforementioned menial tasks. I also used it on stage for live performances to generate midi backtracks and prompt lyrics and chord changes, it was even changing the patches on my GT-6 pedal thru a midi port. The closest to this model selling at the moment is the HP 530 - 2Ghz celeron , 1gb Ram, 120Gb H/disk costing R5k.
In CT I always buy from these guys
