Hey finally, someone that comes from the same place I do....He he
The going price for a 100 gal
100 Gallons 60x22x20x3/8" Tank- $480.00 Tank & Filter- $580.00 Tank, Filter and Canopy- $690.00
This brand new w/ no scratches.
Scratches would not be a good thing and you can almost knock 50% off for being used. If it is with filter and stand/canopy, 300 sounds good...
If not and it is just the tank, I would take the advice of others and wait for one to show up in the news paper or get glass. Much cheaper. One of the chains around here has 110 gal
All Glass aquariums for $169 by itself...
