More spur of the moment???
I hope you're not doing it in a backyard or forest cause encounters with the police/RCMP/ERT are never fun.
I would say get $100 and buy a .177 pellet pistol for plinking pop cans or paper targets or w/e.
Otherwise go to wally world or CT, pick something and just play around with it until it breaks. Springers tend to be pretty reliable but the one at CT I've handled once and I would say it's probably not worth the money, like it's decent but like buying store brand cola, sure it may be cheap but it's low quality and probably worse for you than Coke or Pepsi and definitely not worth it (if you like quality).
