The way i look at it, if they are mods i would do anyways (color dmd, shooter rod, my preferred art blades, shaker, mods i’d do anyways like the JP tower).
Some good mods are also discontinued.
-it sweetens the pot
Toppers being the obvious exception. They add at least their msrp in most cases.
Stuff that i don’t like and are annoying to undo, i usually just move on.
