The Top Speaker for less than $500

Looking to get a new pair of speakers. The budget is not amazing but I think there is some good speakers for this prizes.
My top selects are:
AXIOM M3 V3
APERION INtimus 5B
PSB B6 or B5
PARADIGM Mini Monitor or Atom
MONITOR AUDIO BRONZE BX1

Hope you guys can advice me on what to buy and if someone know second hand or good places to get them it will be perfect.

Thanks
