Any of that look appealing? And that's without extreme effort (it can get much better). There are two reasons I don't tend to smith - it takes a bit of effort, and it makes the game too easy. However for certain challenges, or for primarily melee chars, it can help, especially for the tower, and is very easy to get good results from in a short enough amount of time.
You don't have to lug an anvil, pick axe and ore everywhere - best to stash them somewhere. Ore is easy to acquire by pacifying a level and digging the whole place out, and there's methods to get infinite pick axe repairs at a cheap price (though I generally find enough).
