See my response above. Normally I refrain from telling people to up the budget since I despise when it's done to me. Often I've set the top end because it's my absolute top end. In this circumstance, I think it should be upped. If you are seriously considering this to be a part of your SURVIVAL, then I'd head a little north. I started with your same idea and then found my Ruger, which was a tack driver, started to open up after a few thousand rounds and became a tin can pinker that I still enjoy, while my others (hw97, hw80, hw30, d48, r9, asp20) all stayed as accurate as they were, or improved accuracy over time spent shooting them.
My advice would be to get 2 items. One can pinker for cheap fun, and an "investment" in survival. To me, it's like having a small tarp as your tent in your survival pack....it may function but is it even worth the weight in the pack? I instead got a decent, tiny, insulated 4 season 2 person tent that weighs almost nothing. Sure it was more than the tarp (which has stayed in my trunk anyway because of its utility), but it is WAYYYYYY better for actual rubber meets the road survival.
