I don't know were everett is i think it's mass but not sure. If east cost i would say 3 bills used unless acrylic then i would say 450 is reasonable. If it is just the tank stand and hoods i Just sold a 125 6'18"24" i think for 3 bills actually 250 in the end and took allmost two months to sell. Good luck with the sale man if you are selling.
Everett is in mass, near boston. If you are considering selling, post up a pic. I know I would be interested and there seem to be many others from the area too.
