Using the search and filter functions on Blade HQ of 2" to 3" blade, price $50-$100, and then selecting all the one hand opening types, along with selecting all the lock types other than liner lock (and non-locking, of course), yields nearly 500 results. That excludes some options under $50 that I'd put up against some folders that cost more than $50.
If you like your rescue, the Salt 2 is basically a rustproof Delica without liners. The tip on the Salt 2 is also more rounded, so it's stronger and a bit more rescue knife like. That would give you an LA legal knife that would be practical for other things like fishing, going to the beach, etc. It's just over your budget at $96 -

https://www.knifecenter.com/item/SP...ng-knife-lc200n-plain-blade-green-frn-handles. Those recommendations are because H1 has better edge retention in serrated, and LC200N has better edge retention in plain edge. If you want a $30 knife that's no skin off your back if you lose it, or an overzealous cop confiscates it, then the Cold Steel Tuff Lite -
https://www.knifecenter.com/item/CS...olding-knife-plain-blade-blue-griv-ex-handles is very Spyderco like, but with better build quality than Spyderco's similarly priced Byrd budget line knives. The Tuff Lite is also made in Taiwan vs. mainland China like the Byrds, and I like the friendly looking blue handle that I linked.
