Choose PayPal option. I have sold several gadgets and PayPal payments were instant while their company check took 3 days to arrive. Everything else was good though.
There are sketchy websites that buy your laptops so I was a bit wary about sending my laptop. These guys exceeded all my expectations. Quick turnaround and prompt payment. Thanks.
I got my money confirmed the same day they received my desktop, and they immediately emailed me to tell me that my money is on the way. I would choose them if you have an old device to sell.
