The forgotten tier of fountain pens! Great pens under $75 from Pilot, Sailor, Platinum

It's always seemed strange to me that people gravitate towards both the lower end and higher end of pens from these Japanese brands. The under $30 pens are very popular (Kakuno, Plasir etc). The over $150 pens are popular as well (Custom 74, 3776, 1911 etc). What about the pens in the middle?
