Do your spellcasters not spend a large portion of their wealth increasing their main casting statistic? If they do, then they are not spending extra money on the belt, they are merely reaping an additional benefit from wealth they would have spent anyway.
Nope. They spend *some* weath, but nowhere near all. In fact, at 9th level, with my 32k worth of GP, I spent only 4k raising my character's int. I like being more than a one trick pony.
And, while I'm on this point. If I'm playing a Wizard, and for grins and giggles, I *am* spending all my money on raising my INT, a monk's belt really doesn't do anything for me, does it? In fact, depending on my character's Wis, she might be better off spending that 13k somewhere else.
In fact, any character other than a Wis based spellcaster, is probably better off spending all their money on their prime stats (Fighter on Str/Con, Rogue on Dex, Sorc/Bard on Cha)... so, the belt really doesn't do much for them either.
And, given the wealth by level guidelines, I've already shown that actual armor and shield is definitely more versitile with ~75k (I don't know what level that is, but it's around 12-14 I think) than bracers of armor +8 and a monk's belt is. And even Bracers of armor +6 and a Periapt of Wisdom +6 (which is even more expensive than the bracers +8, yet only provides a total AC bonus of +9...)
