First Developer lasts quite a while, both the working tank and replenisher. Both in small amounts in glass bottles for home processing, and large floating tank for dip and dunk (which is what I do here at work now).

For 25646-71-3 the data on different chemical website databases vary for that exact same CAS number and the molecular weight varies between 200 something g/mol to 800 something g/mol depending on which site you're on, so it can be annoying. Both 24-567-76-8 should be the 800 something version with a lot more sulphuric acid attached to it.
Here is one http://www.alibaba.com/product-gs/256474150/CD_3.html
There's also some companies that'll do direct b2b in smaller quantities I think it's an Indian one, with it's own site not through Alibaba.
