I found a handy set of charts from Fitz's HERO System Stuff link under Misc. HERO System Links. His charts include:
-Impairment Effects
-Disabling Effects
-Bleeding
-Recovery Time
-Combat Maneuver Tables
-Hit Locations
-Special Hit Locations
-Strength Table
-Encumberance Table
-Throwing Table
-Sense Per. Modifer Tables
--Skill Roll Mods
-Contacts Mods
-Range Mods
-Time Chart
-Mental Powers Tables
-Falling and Velocity Tables
-Object BODY and DEF Tables
-And a few others
Seems pretty complete, but I think I'm still going to buy a copy of the System Resource Kit.
