It depends ....
Firstly - I have to completely disagree with the post that says you will shoot no better with a fitted gun and stock fitting is a waste of money. I happen to believe quite the opposite. So do most of the worlds shooting coaches, best gunmakers, most if not all gunsmiths and the vast majority of thinking shooters.
You WILL shoot better with a properly fitted gun - and IT IS money well spent.
Secondly, if you are fairly conventionally sized, need a standard(ish) LOP, and are right handed/right eyed, I would buy a standard stock gun - and go to a good gunfitter and have it altered to fit.
If however you need a very long LOP, or other unusual dimensions, it would be worth thinking about a custom made gun.
What I would do FIRST is visit a good gunfitter, get some measurements, discuss the issue with the gun fitter and see if its practical to alter a standard stock gun. If not, you have to weigh up having a custom built item. Remember that you can see the wood of a standard gun before alteration and choose the wood from stock. To choose a blank and have it made for you will be expensive and involve a long wait.
See that gunfitter first - if necessary more than one - and talk it through with them - as they are experts at this sort of thing.
