I think if you are upfront with the dealer and let them know you need to find a certain piece of gear on the cheap many will help you out and give mini auditions with the understanding that you'll be buying something from them down the line or even that day, just not the major piece you're really interested in.
but to waste a dealers time knowing you have no intention of buying from him sucks. even if the guy is a jerk. it just makes you one too.
i also think dealers feed on your enthusiasm to learn. they'll go out of their way for someone who really wants to learn from them and listen to what they have to say. some wont let you leave the store w/o making you demo gear they know you cant afford if you hit it off with them. it's all about style and relationships. if they're not into that then they're the wrong people anyway.
