Imbuing is now a 1 minute action... at least with that, you don't have your master crafter that come and each time he sees a monster, he enchant his weapon with Bane. The 24 hours seems still a bit long, but I would wait after judges comments on that before doing any modification if I were you.
I like the 24 hours. I see Imbue Item as kind of a way for Master Crafters to always have a powerful magical item on them. And since they're Masters, their magical items are better than most; specifically, they're more versatile. But that doesn't mean they have a constantly morphing sword of Bane. It means at the beginning of the day, or before a big planned encounter, they can prepare themselves by Imbuing their armor or weapon, or perhaps imbuing an ally's. If we reduce the duration, I would say we should up the number of times per day it could be used, because this is the MC's only combat ability. Okay, that's not entirely true, he gets a few levels of spellcasting, too. But he also loses some spellcasting power (2 levels, to be exact) while taking this class.
I think it's balanced, though I haven't playtested it or anything.
ON THE NEW PROPOSAL
When a master crafter level is gained, the character gains new spells or powers per day as if he had also gained a level in any one spellcasting or psionic class he belonged to before he added the prestige class he belonged to previously.
This is incorrect, because it's every ODD MC level, not EVERY level.
Master craftsman.
A master crafter gains a competence bonus on any craft check equal to his master crafter level. He also receives a competence bonus to his effective caster level to meet requirements for crafting magical items (such as the caster level requirement for crafting magical weapons and armor). This does not influence the caster level of spells cast or powers manifested for creating a magical item.
The bolded line doesn't specify the size of the competence bonus. We both know it's the MC level, but you need to word it properly.
ON IMBUE ITEM:
I think we decided that 14,000gp was too much. Drop it to 5,000gp?
If an item already has an enchantment bonus, any enchantment bonus added by the imbue item stacks, but only with the item's own enchantment bonus.
This is unclear because what you refer to is actually the "magical enhancement bonus" not the enchantment bonus. Try this:
If an item already has a magical enhancement bonus, any enhancement bonus added by Imbue Item stacks, but only with the item's own magical enhancement bonus, not the enhancement bonuses from masterwork items or those granted by spells or abilities.
---------------
With all that fixed, I think I'll start the ball rolling and vote
YES to this PrC. The things that might still need tweaking are the Imbue Item power limits: the gp limit, and the max-modifier limit. My vote will stand through all changes in the "nerf" direction, but I'll have to reconsider if the change is in the "more-powerful" direction. (I actually think 14,000gp is fine. It's not exponential like real character wealth is, but its simple.)
