Sailor KOP Ebonite, or save up for an MB Great Characters?

[Le.Pen.Supremo]

Hi there! There’s a local pen show happening in a few days and I want to hear some thoughts. I have been wanting the Sailor KOP Ebonite for two years now and I wonder if it’s worth getting. Will the ebonite body last for a long time (with proper care of course)? I’m afraid that the ebonite might easily discolor or lose its shine (one of the main reasons why I like it) after a year or so and that it might be too fragile. Or perhaps I should go for an acrylic version? 
 

On the other hand, my ultimate grail is the Montblanc Great Characters Enzo Ferrari. But it’s a bit far from my budget right now so I need to wait for a few months if that’s the better buy. 
 

As much as I want both, I will only be settling for one pen in the near future as I want to focusing on other things. 
 

So KOP or MB Great Characters? Let me know your thoughts!

Buy the one that makes your pulse race or your heart sing. Judging from your post, that sounds like the Montblanc Great Characters Enzo Ferrari, which you've described as your 'ultimate grail'. Go with your ultimate grail, even if you have to wait a few months.

Although they are different pens I don't believe one is objectively better than the other. So this comes down to a personal choice. Which one is the one you think about first? Which one would you feel bad about if you didn't get it?
