It only took me about 10 minutes to make my first 64k. If you plan ahead, crafting isn't difficult. That is unless you are working with unstackable items. That is when crafting becomes tedious and boring. Multi-step crafting procedures can be calculated ahead of time. That little bit of math will save you a lot of manhours, re-putting items into the crafting bench to recraft an item you made a couple minutes ago, because it was required in another step.
If you have an AE system, take advantage of the MAC. I've saved myself hours of time spent crafting, allowing myself to do other things and I'm not even exaggerating. It's nice to run by one of your access terminals, located in multiple locations, check on a few things, order a few hundred or so scented paneling, a stack of diamonds, 30-40 iron OR gates and a couple hundred other items in preparation for the next step in your project, then go do something else and have it all done for you.
The most tedious item I have ever crafted was probably the 70 or so harvesters I made by hand (without AE). Shears do not stack, golden axes do not stack, it's obvious where I'm going with this.
