Ya know, I can understand where you're coming from... Meaning both sides...
Personally, I don't have a use for a break action single shot rifle. But have I bought one on a lark (more than once)? Yup. They don't shoot great, but well enough for a little hunting. And for $120 that I wouldn't really miss, they were worth the fun, and I kept them in the truck and didn't feel bad about scratches.
I have a $300 Winchester 94 Trapper .30-30 that I bought for the same reason. Hate toggle link actions, don't really like the .30-30, but for the price, and the length, it was exactly what I wanted. It rode around behind the seat of my truck for years, and it still gets a few opportunity shots a year at coyotes or rabbits. I wanted a turd-gun, so I bought a turd-gun.
Got a single shot .410 Snake Charmer that used to live behind the seat of my truck too when I was working a lot in western KS. Worthless paperweight these days, but I shot the heck out of that lil thing for several years.
Got an SKS last year for $250 because I wanted to get another one (again) like one I had in high school. It's not accurate, it's ugly, and I have no use for it. Just a fun rifle.
They all fit in the safe, and I do end up shooting all (or at least most) of them over the course of a year.
But, I have a side-stream of disposable income that lets me blow a little money on worthless stuff from time to time, and I have better rifles to depend on when I need something more accurate.
I would NEVER recommend many of the weapons I own to a new shooter, and would ABSOLUTELY agree that if a guy is starting out (see my comments on PredatorOnPoint's recent posts), he's better served by not wasting his money on sub-standard gear, and rather than buying a "good enough" rifle, he should save that money towards a better rifle. But not everyone fits that paradigm.
