PEOPLE ALWAYS OVERESTIMATE! get over it already. if i spent 836G on a twink or whatever, and if someone ask, i more than likely tell them 1k. i doubt anyone really keep track of their spending.
just before patch, i sold a libram constitution for 400G and a nethercobra for 600.. nethercleft & clefthide for 400G. prices varies on different servers, but if you looking to make a twink you should expect to fund 1K "ATLEAST" to that character
pre-3.1 a monkey 5/5 legs could sell for 100G.. 4/4 monkey gloves 100G.. forest leather bracers 50-100G. and a wrangler 3/3 500G. the wranglers might seem high but throughout my entire WoW career... i've seen more Shadowfangs on AH than i have seen 3/3 monkey wranglers. not to mention boars speed on your fishing boots.
it all falls down to how populated twinks are on your server really. those are the prices the items go for, you can be lucky and find them on AH for 3G each.
i do agree with the OP since the patch ive seen alot of QQ'ing in trade chat.. and some people even lvling to 59's now. to be frank i seem to be one of the few that loves this patch. skills actually play a factor now, and for the first time level 31's-35's are actually being effective in a BG.
i do feel bad for those who dedicated so much effort into getting the fishing hats/boots, profession skills up, and all the caster classes ;[
