Well it is acrylic with a built in overflow.
Which are pretty expensive atleast by me.
If you want an acrylic tank over glass i say go for it.
Otherwise you can get a new glass setup for around the same price.
The stand looks good. And the canopy is a plus.
Knock atleast a 100 off for that scratch, also ask if he made anymore when he took everything out.
What kind of filter is it?
Wetdry?
All i can find is some tube filter by eco.
Also couldn't hurt to call some places and see what a 125 acrylic costs in your area,
