If you want a leather backpack, I like the Loyal Stricklin Rucksack, the Kasperi Fold Top, and the deerskin pack that Matthias Steinhauser makes.
For canvas, you could try Trakke and the GoRuck M23. Cabourn had a made in Japan reproduction of the Swiss Army Rucksack, and he was working on a version with Trakke, but I think that the latter fell through.
There are various Black Friday sales on or coming up. Last year Loyal Stricklin did 30% off for one day only, so keep an eye on their website or mailing list.
I could add a few more brands, like Defy and Filson, but they've already been mentioned.
