I would suggest the Briggs & Riley 17” Executive Clamshell backpack. It may be a little above your budget, but it’s totally worth the value. All their bags come with a Simple as that(R) lifetime warranty, too. I love their luggage collection for style, durability and innovative functions. The Clamshell helps me keep my things organized as I travel. I travel a lot so I love the TSA checkpoint friendly feature in this Clamshell. The computer section splits down the middle isolating the laptop for scanning at security checkpoints. There’s no hassle of taking out, putting in your laptop at every security checkpoint.
