And Your headline says "Looking For $1500 Laptop". Which one do you want - a laptop or you want get rid of your money?
My recommendation - first of all look for a good laptop and if needed, add later as much memory as You want. SSD's are now so cheap and most of good laptops already have two places, ie for traditional SSD and for NVMe. And the new NVMe-s are so small, for example mine is about 2cm x 2cm x 3mm and it's 256GB.
