I know what you guys mean as I am just a yound man in a very gun hostile enviorment myself. We have some terrible dealers in MA, though I do have quite a few dealers around me. All of them will BS you to some degree, either because they think you can be duped, or out of general ignorance.
I have had friends whom I've taken to a gunshop tell me about how they have gone back to that very same gunshop without me and been asked to not touch anything, or to leave because they didn't have their licenese's on them.
I have found that while some will be cranky to everyone and anyone, all will give you more respect and treat you better if you act confident, firm, serious, while showing them that you posess knowledge of guns through conversation.
Most of the times I dind't buy at a shop was not because I couldn't afford something, or not even because they didn't have what I was looking for in stock (some did). It was because that most of their guns (some of their used and nearly all of their new) were way overpriced. The price discrepency between what they want and what I can get from other sources was simply too high to bother with.
I could afford any gun in any one of their stores. Heck, I spent over $3000 on guns the first year I could legally own them and have continued to spend $2000+ per year on them every year since that. I am able to do so because I always work hard throughout the year (esp. during the summer months that I have off) and put my money toward guns instead of food (going out to eat), rock concerts, CDs, jewlery, cars, booze, and the other junk that young people typically like to waste money on. I know kids that blow $50-$200 bucks EVERY weekend "having fun" and "partying".
Conserve your money wisely, work hard, and you'll be able to buy any gun that you're little heart desires.
Might as well buy the guns you want now while you don't have bills to pay, yourself and possibly a family to support, etc.
