Well, as an experienced player, I don't really agree with this. The extra money spent on a higher end gun goes towards quality and reliability. What that means to me on the field is this: Every time I pull the trigger it will shoot a paintball and it will not break during normal use.
Spending more money on the high end stuff doesn't make me any more confident in myself. For instance, I own two pump markers. Playing with them against semi's is a handicap. By your reasoning I should feel less confident when playing with a pump than with a semi. But I don't. I'm plenty confident in my skills to go out on the field with a handicap and still play.
And that's the whole point. One's skills are what's important. The fact that many people play just as well - if not better - with a pump as with a semi, to me, is proof enough.
like i said most players have do this for this reason, i know there are other reasons people buy expencive paintball marker and equipment, for example, quality, reliability, and how well the company is known. but when you think about it, imagine giving a new player a stock spyder or brass eagle with crap or worn out equipment, chances are, he will hold back because of efficancys in the gun and gear or the fact he knows that company is known for having low quality equipment or have a bad rep. now give that same player high quality gear for example, an ego, bob long, dm series, or the so called legendary ANGEL!!!! chances are the player will take greater chances or gain courage in maybe moving up to the 50 or what not. true it may not be this way with everyone, i know many people who've used a variaty of markers, from a pump brass eagle talon to a special edition ego or something like that. but if you think about it. if you put yourself in a position where you have a brass eagle or a spyder and are using things like sneakers and baseball padding, and then replace those things with egos, angles, dm's, bob longs, or whatever floats your boat, i bet you can find a noticable difference in things like your morale and crap like that, maybe not much of a difference, maybe things like "**** this gun is jamming on me" compared to maybe a newer player who may have issues like "oh god, people on the other team have really nice stuff, i'm not sure if i can beat them"
