I ended up going with this level 15 ulock with a secondary steel cable until I can afford one of the really nice angle grinder-resistant ones: https://www.amazon.com/dp/B08M6HST7G . That, a hidden GPS tracker, and an alarm system were all immediate purchases. I’m mainly banking on being secure by parking next to more expensive bikes though. That has kept me safe with my current bike and a basic ulock since 2020.
That’s more or less what I plan to upgrade to eventually if I get a lot of value out of the one I just bought. There’s so much great camping within an hour’s drive, and minus the lack of bike lanes it seems like it’d be much more fun to bike those canyons than do the really stressful drive.
