|Are these sets absolutely necessary to build your model? Well it all depends how much detail you want to have on your model. Each set costs $10.50 USD based on the North Star Models pricelist,
which is very good considering that you get enough to equip several ships. Having these fittings will enhance your model so I would recommend getting the one that would fit your needs. These two
sets can be purchased directly from North Star Models or from Freetime/Pacific Front Hobbies and White Ensign Models.
