My first year in high school (US) I bought a used “German Mountain Rucksack” from a military surplus catalog. Heavy canvas, rubberized top and bottom, triple stitching, buckles and drawstrings instead of zippers.
I used it all through HS and college, and I’ve taken it on dozens of flights across the country and overseas. I’ll frequently load it up with 40lb of groceries and bike home from the store. It looked like it had gone through a warzone when I got it (and in all probability it has) but even after 20+ years of rough use it’s still going strong - so that’s my vote.
Been using racknerd to host my tiny stupid websites for a couple years, it’s great value for money and a fantastic way to learn sysadmin stuff. I also appreciate that they give a lot of heads up for auto-renewal and don’t escalate pricing on renewal.
