yeah, my current carry on is not end of life - but i really like the blue torq one. my laptop backpack is the same brand too.
the lowest end carry on i have is still pretty nice - a 20" travelpro. i have a 20" roller, 21" spinner, and 22" roller that are all carry-ons. my own bag is a 22" and i've never had a problem fitting it on a domestic, never tried international but it should fit most/all of them too. roller = 2 wheels, spinner = 4 wheels and can turn in any direction. the 20" is my cheapest piece:
