Looking for a good condition laptop for the implementation tasks of my own Drone DIY and Security Monitoring Systems - Qiubo Su

Hi All,

(update)

I have been Looking for a good condition laptop for the titled tasks for quite a while from www.trademe.co.nz... but so far haven't found one suitable for the tasks (design, configuration, tuning, testing and being used for my own Tech businesses. already independently going through the 1, 2, 3, 4 steps before by myself alone, now wanting to iterate the process again and again for continuous improvements with the right tools) I planned for and within my budget, so I'm here to give it a try.

Requirements for the laptop I'm looking for:

1) Intel Core i7 CPU with Virtualization features, 8+GB RAM, SSD storage
2) Nvidia or AMD graphics card, Ethernet Connection 1000, SIM card slot, 4G LTE capabilities
3) Strong battery life, Windows 10 Pro OS
4) Light weight, including power adapter
5) Budget < $500

I have been multi-tasked working on the other Tech tasks I planned for myself, so I'm able to wait for, and start the other Tech tasks when they're ready and being well prepared. I'm my own Boss. I make plans for myself.

Best regards,
Qiubo Su
