The only ones that are not worth a purchase IMO are the ancient ones like the shinkouchou Kabuto line, both because it's exorbitantly overpriced and that the model itself is outdated. I have shinkouchou dark kabuto and while the make is still good, it's not comparable to the more recent releases and definitely not worth paying 600+ USD for it.
