I'm sure that Benny will take a good look and report back before he does much with it. If he says the diamond is shot/well used then you can make an informed decision. If the diamond is good, then a simple and cheaper rebuild is in order if cost is of prime importance.
If it needs replacing, then Axel is your man and you will have a shibata diamond which you know the condition and amount of use it's had. For the extra cost and security of mind - as well as quality of vinyl reproduction, I still think I'd lean towards Axel.
