Oh man, as the guy playing the wizard in our last game, I would have loved it if I could've wheedled myself an extra share of treasure.
The best I could usually do was to get the party to kick a few hundred gp into pearls for Identify spells before the loot was divided up so I wouldn't end up paying for it all myself, and to be excused from having to pitch in for the price of party resources like wands of cure light or cure moderate wounds. But between paying 100gp/page just to put spells in my book, paying for the spells I was putting into the book, buying other expensive material components, and then trying to pay for "must-have" scrolls and items, I was still the poorest guy in the whole party. Wizards are a terribly expensive class, if you actually want to exploit their versatility to its fullest.
Though I'll admit that I ended up having as much (or more) items as the rest of the group, in addition to the fantastically expensive spellbooks. Partly this was the usual discount for crafting things yourself, and partly it was because the campaign setting made it clear that any wizard or cleric who accepted a commission to craft items for a PC generally charged two or three times the market price for the service; so while everyone else was hoarding their treasure to buy stuff at an insane markup, I was able to make items for less than they were worth and even insanely overcharge a couple of NPCs to get some additional cashflow.
...mind you, the tradeoff was that I ended up over two thousand xp behind everyone else, and still flat broke because I could spend the money much faster than it came in. But even though I was always strapped for cash and lagged behind them in levels, at least I had the same overall value of possessions (or higher) as everyone else, plus a good selection of utility spells to draw on.
