Hey Chops, just a note about this.
I did a little "research", and it's not that Thottbot doesn't have these items in their DB... it's that it doesn't have those items with their modifiers.
Fro example If you search
Lazuli Ring of Spirit you get nada mucho. However, just searching for
Lazuli Ring works.
"Great, I KNOW it's a ring... what's it DO for me?" The problem? Almost every item has a random modifier, and the "base" info of these items isn't helpful at all, unless it's an armor item and all you care about is the armor value.
I think it's definitely time to change DBs. Truthfully, you could probably start you own with the number of peeps that regularly use your services. Just have everyone import their Item cache. You could very quickly support your own item lookup. Heck, you aren't using the Item Image textures anyway, so the item cache so be plenty for you.
**On a side note. I've already begun designing (almost finished) an item DB in MS SQL 2000. Did it back when I was making my own Guild site, before I swtiched guilds. I could send you my Erwin database modeler diagram if you desire. Could take some of the work outta the development for you. (Of course, you'd be free to modify it as you see fit). On the other hand, another alternative is that I can open up my DB to the web, and you can just use mine. It's empty of data, but I could basically make it FOR you according to your needs, and then we could work out a DKPSystem import functionality for the itemcache files. Unlike thottbot or Allakhazam, this would really only be used by you. The difference being that they have an established item list (though clearly Thottbot is problematic ATM).
[EDIT]: Now even Lazuli Ring doesn't work... but it did awhile ago. Hmm... their system is wacked.
