Put the extras out for all to see and sell them with the late. Part of selling is giving a good deal and not screwing every penny from the deal. It would be far more attractive to a potential customer as it represents an instantaneous start. I would be reluctant to buy a bare lathe, but would be willing to pay more for a lathe complete with tooling, for a starter kit as it were. It’s nicer to deal with a generous person than a tight arse. Infact I’ve called off a deals because I wasn’t impressed with the fellow. And I’ve tipped luck money to a good soul as part of the action.
I agree with the general consensus sell all each for the most money and a time consuming hassle fair enough. All together makes a happy customer who has paid a bit more for the start accessories allow. A happy customer is better than cash alone
