Newbies need encouragement and guidance in an interactive way with folks that have been around the block a few times. Whenever they post here for the first time, this is the first thread of this kind for them. If forum members get tired of reading these sorts of threads, making them aggravated and cranky, maybe they should just take a pass on reading any threads about getting a first bass. Seems simple enough.
In a great many cases, a young musician just getting involved with a large intimidating instrument for the first time is very ambivalent about it. They learn to fall in love with playing these musical hippos over time. Each of us has the power to help these folks out at the start, even just a little bit, with a little patience and some words of reassurance, not lectures and attitude. Let's make the doublebass world an even nicer place than it already is.
I agree that newbies should be encouraged in a friendly manner. I've spent a fair amount of time trying to help newbies find new instruments. If the comments I've received are any indication, I've been successful at patiently helping. I tried in this thread as well. (Steve, I'm not suggesting at all that you were including me among the impatient. In fact, I assume that you weren't.)
With regard to ambivalence, the advice I gave the OP, and by which I stand, is that success with the DB is not something that's likely to occur if it's something that one is, in a sense, forced to do. The OP did clarify and it seems that he's committed. I think he's been given some very good advice regarding where and how to look for a bass and he seems to have appreciated that advice and taken it seriously. That's all good.
So, where's the rub? I think what several members find annoying is the failure on the part of many newbie posters to lift even one finger (e.g., to click a mouse

) to take advantage of the wealth of information offered to them before they post. Given all the stickies and instructions at the top of the forum, one wonders how and why some folks ignore them all and post what amounts to "I want to buy a bass. Will $1000 do it?" I agree that when that happens, it's best to take a breath and point them to the wiki. Still, the "me generation" need to be spoon-fed an answer right NOW can be trying. I think newbie posters do have some responsibility to read a bit and learn about the forum before banging out a first post. That can be politely pointed out to them while providing useful links. For the most part, that's what happened in this thread. As I see it, compared to some other similar threads, there was very little contention and a wealth of on-point information offered.
Contrary to what a minority assert, I don't believe that there is, in general, condescension toward those searching for instruments on modest budgets. In fact, the vast majority of graciously-offered advice and direction in these threads seems to be about the purchase of basses priced at the lower end of the spectrum. We sure talk about $1,500 purchases more often than $20,000 purchases!
