Items or feats to increase HD of summoned monsters

[Thac0 Redeye]

Hello all, I am currently playing a sorc who just got 5th level spells . I want to know if there are any magic items or feats that will increase the Hit Dice of summoned monsters. I just added "Vicious summoning" from Book of Eldritch might. (all core books, FR,BOED, BOVD, completes, races of, and environment ie sandstorm. NO Ebberron)
Thanks

Check the malconvoker handbook, which also has links to the summoners desk reference iirc. http://www.minmaxboards.com/index.php?topic=2791.0

that last one has a bunch of links at the bottom, that may be useful

but I don't think anything adds to HD of the summoned creature, except I think there is an ACF in mongoose publishing' Quentisential Wizards handbook
