I have this one. Bought when it was half-off, so $20. I actually bought it from Microsoft. I think it was on clearance because they did not have any listed anymore.

By any chance, are you near a MicroCenter? They have excellent in-store deals for things like this. They even give lil flash drives away as promotions; sometimes BT headphones, and things like that.

EDIT: Oh shit, I found one half-off, and SanDisk: https://www.amazon.com/SanDisk-128GB-Android-Devices-Computers/dp/B01M0QR22B/?th=1
