I would suggest you the next mods: Too Many Items(Recommend)----Storage Mod(Optional)----crossbowmod(Optional)----IndustrialCraft(Recommend)----BuildCraft(Recommend)----PowerCraft(Optional)
I could not find one. The Buildcraft 3.7.2 that some sites says is for 1.6.2 isn't. It's for 1.5.2 just like it says on his site that's the first page in my link.
