Some people simply use old info for Biochem skill - few patches before it used rare mats from UT now it uses Diplomacy.
No surprise there, esp if they are copying other site's with older info.
Just glad to know the current status before gettting in and investing time/money to do it.
The more I think about it though, I may do the Slicing/Investigation/Treasure Hunting thing on my main to feed credits to alts who will do the actual crafting work.
May not be able to buy everything with money, but for most things I think it would work out on in the long run.
