Scouring the surface for barrels is not the best idea, unfortunately. Whilst you can find a few in the open, they are far from being common. Instead, if you want to start stockpiling new keys you are going to need two licences and three pieces of equipment.

I know when I've gotten a case in the past and needed a key, I could buy it directly from steam for $2.49. Is this not the case for all keys? Since some keys go on the market for $6 or even $8, I can only assume that you can't buy them directly for $2.49 anymore, right? I mainly ask because I have a revolver key that goes for around $6.50 right now, but if I theoretically sold it and bought a revolver case, could I just re-buy the key directly from steam for $2.49? This obviously wouldn't made sense because you'd be able to just generate money...
