I've seen a few sales recently on the 1st gen Pixel 128GB around that price range. It even has a headphone jack. There are no exceptional corporate sales on them at the moment.
Amazon has some for $353 new, or $269 "like new" from China.
Here's an eBay sale of the Pixel XL 128GB for $301, but I've read a few complaints of people having charging problems after updating the XL to Android 9. If you prefer a new 5-inch Pixel, it'd be worth keeping an eye out for more sales if you're in the market. There's bound to be another sale sooner or later. I'm extremely pleased with mine.
It takes pretty good photos, too. And for 1st gen Pixel owners, Google offers
free unlimited cloud backup of full resolution photos and videos for life. The Pixel 2 only has it for 3 years, then users must settle for reduced-res backups.
