IMHO his video is kind of wandering- why is "collecting" OK but buying guns for the sake of having them is not? I don't really get that.
One point that he should have made which actually bears fruit is the greatest danger in having GAS is that some of your guns invariably can "suffer" at the hands of your "addiction." For example- that bolt action rifle you might have- that you could never afford the PROPER glass for, that sucks ass because you keep s**ty glass on it... that gun SUFFERS because you went out and bought something else you didn't really need. (been there, done that, got the "I am a retard" t-shirt) As a sufferer of GAS that's the problem I've run into the most. Having less guns + better goodies on them = winning. Having lots of poorly outfitted guns = fail. When the latter happens you end up having all this crap around you never want to take to the range.
I say this as being someone who suffered from a lot of GAS. I've bought and sold way too many guns over the years, and if I could have done it all over again, I would have saved a lot of money.
I find nowadays I make a LOT less impulse buys than I used to. Almost none. If I had any advice to a new shooter, it would be to try lots of other peoples stuff (or go somewhere and rent it) and see what you like before you actually commit to a purchase. You'll save a s**tload of money that way. The other piece of advice is you don't get something for nothing. If you buy a cheap $125 scope from the chinese optics guy at the gun show, because you don't want to spend $300-$1000+ on a real scope, it WILL be a piece of shit. Don't pretend, or delude yourself into believing that it's not going to be. It will fail or be miserable and it will mock you every time you take it to the range. If you sack up, and buy the good stuff you will generally cry only once. The same goes for guns, too. If it looks/seems ghetto, it probably is. If you have this burning desire to buy junk, just take the money you were going to spend and buy ammo instead. You'll be better off. If you have this vacuous burning desire to buy some random gun just for the hell of it... don't do it... buy ammunition instead.
I realize I'm sounding like a party pooper, but you'll thank me later.
